Key Information

History

[edit]

The company was founded in Berlin's Kreuzberg district in 2000.[1]

VeriSign was a successful internet security company that had a series of product lines that connected mobile network companies' text message networks together securely, processing about 3 billion per day in 2004. VeriSign CEO Stratton Sclavos recognised that with VoIP products developing, the revenues could decrease, and so he hired Vernon Irvin as Executive Vice President and General Manager of VeriSign's Communications Services division to solve the problem. Irvin saw good but technical and expensive products, but saw the volumes of exchange over the system as the solution.[2]

In late 2004, under Irvin's direction, VeriSign bought Jamba for $270 million. Jamba at the time built mobile applications, games, ringtones and wallpapers, and was also in over 40 countries worldwide. The VeriSign team had recognised that there were twice as many mobile phones as there were computers, which also had built-in computer technology. Effectively, VeriSign now had a new content distribution platform which also integrated with the internet, which was both secure and auditable—now all they needed was the content.

VeriSign relocated Jamba's HQ Office to prestige premises in the Dom Aquarée building near Alexanderplatz in the centre of Berlin.

In 2005, Jamba started doing business in China.

While Irvin sourced content, Jamba became Jamster in the United States. Irvin struck a deal with Kevin Liles, President of Warner Music Group, to provide mobile consumers with early access to hip-hop artist Mike Jones' debut album "Who Is Mike Jones?"—in return, Jones created the first artist-endorsed Jamster ring-tone advertisement in the US. When "Who is Mike Jones" was released it debuted among the top 5 albums on the Billboard charts and went on to sell over a million copies. The Crazy Frog ringtone did the same in Europe.[3]

Jamba/Jamster boomed—when VeriSign bought the business it had a turnover of $15 million per quarter and 3 quarters later this increased to $150 million a quarter—in 2005, the company made close to $600 million in revenue. VeriSign expanded Jamba/Jamster by the acquisitions of UNC-Embratel and Unimobile. Jamster also added to its revenues by adding "impulse purchasing"—when you downloaded one ringtone, you were offered others. This turned into interactive advertising, for which the mobile owner was charged, sometimes unknowingly. This created controversy in Europe, and was quickly withdrawn.

Later developments included a collaboration with L'Oréal encouraging users to send in photos to find 'America's next supermodel' and promoting VeriSign Back-Up as a mechanism to re-download music tracks a customer had previously bought to a different mobile phone, for example if the previous phone was stolen, broken or lost.

On 12 September 2006, News Corporation announced it would pay approximately $188 million for 51% shares in Jamba! and would combine it with Fox Mobile Entertainment assets,[4] such as Mobizzo, with Lucy Hood, formerly President of Fox Mobile Entertainment, becoming CEO of the joint venture.[5] On 23 October 2006, it was announced that Vernon Irvin would join XM Satellite Radio as Chief Marketing Officer.[6] In late December 2010, Jesta Group acquired Fox Mobile Group from News Corp. Jesta Group renamed the mobile services company to Jesta Digital.[7]

Controversy

[edit]

Jamba! had drawn criticism for allegedly misleading customers in its service advertisements. In general, Jamba! services were sold as a subscription, despite advertising that seems to imply that customers are buying a one-off phone ringtone. The company drew criticism for making it difficult to unsubscribe; for example, during December 2005, Jamba!'s German website FAQ did not mention the SMS code needed to cancel all subscriptions.

Jamba! advertised aggressively on youth-oriented channels such as MTV and German VIVA. In 2004, it spent €90 million on television advertising in Germany alone. In Jamba! countries in Europe, it was not uncommon to see a multitude of the same Jamba! commercials on television in the same commercial break. An online petition in Germany protesting against the firm's advertising practices drew some 200,000 signatures.[citation needed]

In late September 2006, television channels MTV, ProSieben, RTL II and Viva cited ethics concerns over refusing to air Jamba's advertisement for a Hitler themed SMS-downloadable cartoon titled "Der Bonker". Illustrator Walter Moers's short film depicts Hitler in toilet humour scenes with his dog Blondi and three German uniformed rubber ducks.[8] The work had earned criticism from some Jewish memorial groups and politicians, while garnering praise from others.[9]

Jamba (formerly Jamba!, also known as Jamster in some markets) is a German company that creates and markets ringtones for mobile phones. Founded in the Kreuzberg district of Berlin in 2000, it specialized in mobile entertainment content, including ringtones, games, and logos, and expanded internationally under various brand names.

History

Founding and Early Development

Jamba! was founded in August 2000 in Berlin's district by the Samwer brothers—Marc, , and —along with Max Finger and Ole , capitalizing on the emerging demand for personalization services such as ringtones, wallpapers, and games. The company partnered early with telecom providers like Debitel to distribute content via and WAP, targeting the rapid adoption of color-screen feature phones in . Initial operations focused on aggregating and licensing for mobile delivery, with a centered on premium billing for downloads. By 2001, Jamba had expanded its offerings to include Java-based games, becoming one of the first European firms to commercialize them amid the rollout of compatible handsets. Ole Brandenburg departed the company that year from his role in marketing and sales, amid internal shifts as the venture scaled. The firm's early growth accelerated through aggressive content acquisition and international distribution deals, achieving significant revenue from polyphonic ringtones and logos by 2003. Jamba's breakthrough came in 2004 with the ringtone, a viral hit that topped charts in multiple countries and propelled the company to prominence in the mobile entertainment sector. This success culminated in its acquisition by on May 24, 2004, for $273 million—comprising 65% cash and 35% stock—which integrated approximately 300 employees and enhanced VeriSign's wireless content capabilities.

International Expansion and Acquisitions

Jamba!, founded in , , in 2000 by brothers Marc, , and Samwer, initiated international expansion early in its operations by distributing mobile content such as ringtones, games, and wallpapers across multiple markets outside . The company entered territories in , , and , often adapting its branding for local audiences; for instance, it operated as Jamster in and the to capitalize on regional mobile trends. Wait, no wiki. From [web:20] but it's wiki link, but content says that. Avoid. From [web:25] Jamster in Australia. Better: The company's growth was driven by licensing deals and direct partnerships with mobile carriers, enabling content delivery in diverse regions including the , , and . By 2003, Jamba! had achieved revenues of $40 million, escalating to $500 million by 2005, largely attributable to campaigns like the that resonated globally. This expansion positioned Jamba! to deliver content in 30 territories by mid-2006. The June 2004 acquisition by for $273 million in cash and stock marked a pivotal step in scaling international operations, as leveraged its infrastructure to integrate and distribute Jamba!'s catalog more broadly. Under , Jamba! benefited from supplementary acquisitions, including UNC-Embratel and Unimobile, which enhanced its mobile entertainment portfolio and market penetration in and . In September 2006, purchased a 51% stake in Jamba! from for $188 million, followed by the remaining shares, fully consolidating control and reorienting the entity toward broader media synergies under the Fox Mobile Group banner. This period sustained international momentum, with Fox Mobile Group maintaining operations in key markets amid the peak of mobile content demand. In December 2010, divested Fox Mobile Group, including Jamba!'s assets, to an investor consortium led by Jesta Group for an undisclosed sum, reflecting a strategic exit as the market matured.

Products and Services

Core Offerings: Ringtones and Mobile Content

Jamba!'s core offerings centered on downloadable digital content optimized for early mobile phones, primarily ringtones and ancillary media accessible via , WAP portals, or carrier billing. Ringtones formed the flagship product, encompassing polyphonic melodies mimicking full musical tracks, monophonic tones, and "realtones" or "truetones" excerpted from licensed popular songs, often priced at premium rates of €1.50 to €3 per download in European markets during the mid-2000s peak. These were bundled with novelty "funtones" tied to proprietary characters like the , generating significant revenue—such as over £40 million from the ringtone alone in the UK by 2005—through high-volume sales driven by limited mobile customization options at the time. Beyond ringtones, included static and animated wallpapers for home screens, operator logos for network displays, and basic graphics packs, which allowed users to personalize devices lacking native app ecosystems. Jamba! expanded into interactive elements like Java-compatible games—simple titles such as puzzle or arcade variants—and short-form video "mobisodes" adapted from licensed TV properties, including clips from shows like , distributed via mobile networks starting around 2006. These offerings targeted feature phones dominant in over 40 countries, with content aggregated from partnerships and in-house creation to exploit SMS-based delivery, where users received links or codes post-purchase confirmation. The subscription model underpinned access, with initial ringtones often leading to recurring fees for content libraries, though marketed as one-time purchases; by , this encompassed wallpapers, ringtones, , and emerging mobile TV, reflecting Jamba!'s pivot toward diversified entertainment amid ringtone market saturation. Peak distribution reached millions of downloads annually, supported by web portals for browsing catalogs tailored to device capabilities, though quality varied due to compression for low-bandwidth constraints.

Technological Innovations in Delivery

Jamba! distinguished itself through its leadership in off-deck delivery of mobile entertainment, enabling content distribution beyond carrier-controlled portals and reducing dependency on operator approvals and revenue-sharing constraints. This model, which relied on direct consumer initiation via advertisements leading to requests, allowed for rapid scaling across global markets starting from its founding in 2000. By partnering with third-party aggregators and billing providers, Jamba! facilitated seamless integration with carrier networks for premium transactions, where users texted shortcodes to purchase and receive ringtones or wallpapers almost instantaneously. The company's proprietary technology platform represented a key innovation, supporting high-volume, multi-format content delivery including monophonic and polyphonic ringtones, graphical logos, and early mobile games. This permitted immediate adaptation and distribution to diverse handsets and networks without intermediaries, handling millions of transactions efficiently. Jamba!'s systems emphasized in content encoding and transmission protocols compatible with early and emerging devices, prioritizing compatibility over carrier-specific customizations. In 2006, Jamba! extended its delivery innovations into (m-commerce) through a with and , developing specialized engines for web-to-mobile downloads. This enabled users on platforms like to acquire ringtones, animations, and graphics directly via browser-based purchases billed through carriers, bridging and WAP technologies for hybrid delivery. Such advancements supported Jamba!'s expansion to video clips and subscriptions, though they later faced scrutiny over billing transparency in off-deck models.

Marketing and Advertising

Aggressive Advertising Campaigns

Jamba!, operating as Jamster in the and , invested heavily in television during the mid-2000s to promote its and mobile content subscriptions, with expenditures reaching £44.64 million in the alone from mid-December 2004 to mid-December 2005. These campaigns featured high-frequency airings, including 73,716 television spots in May 2005 at a cost of £8 million, exposing 87% of the UK population to the ads an average of 26 times. The strategy emphasized youth-oriented channels such as , utilizing bizarre and repetitive characters like the —initially depicted as a anthropomorphic on a —to capture amid cluttered airwaves. The campaigns' aggressiveness stemmed from their saturation tactics and interactive SMS prompts, which encouraged viewers to text premium-rate numbers for content downloads, often obscuring that purchases initiated recurring weekly subscriptions rather than one-time fees. This approach generated significant revenue, with the Crazy Frog ringtone alone yielding over £40 million in the UK by 2005, but drew 298 complaints to the Advertising Standards Authority (ASA) regarding unclear terms. Regulators responded by restricting such ads to after 9pm from September 2005, citing risks of misleading young audiences despite Jamba's claims that only 1.6% of subscribers were under 16. Further scrutiny led to a £40,000 fine against MBlox, the service provider for Jamster's Crazy Frog promotions, after 338 complaints highlighted overcharges from misrepresented subscription models. appealed ASA rulings twice, losing both times, including a challenge reviewed by independent arbiter Sir John Caines, underscoring the campaigns' boundary-pushing nature in blending with direct-response . While effective in driving downloads—contributing to 's overall sales peak—the tactics fueled perceptions of exploitation, particularly among impressionable viewers, and prompted voluntary ad revisions to comply with industry codes.

Iconic Characters and Media Strategy

Jamba!'s media strategy heavily relied on animated characters to promote its and subscriptions through high-volume television advertisements, aiming to embed recall via repetitive, jingles and quirky visuals that prompted impulse purchases to premium numbers. These campaigns targeted broad audiences, including , with ads airing frequently across networks, particularly in late-night slots, to maximize cost-effective exposure while minimizing direct scrutiny. In the UK market under the Jamster , this approach culminated in a £45 million investment in 2005, equivalent to thousands of daily airings that saturated viewers' experiences. The centerpiece of these efforts was the , a wingless green amphibian character animated to mimic motorcycle stunts while performing a synthesized version of Harold Faltermeyer's "" theme from the 1984 film , interspersed with a signature "brrring-ding-ding-ding-dingerrr-ding-ding" vocalization. Originating from a 1997 sound imitation by Swedish Daniel Malmedahl, the character was commercialized by ! starting in 2003 to advertise its ringtones, evolving into a franchise that included top-charting singles, albums, and video games such as released in . The ad's deliberate provocative elements, including glimpses of the character's exposed anatomy, sparked regulatory scrutiny but amplified its viral notoriety, with the Advertising Standards Authority upholding complaints yet acknowledging its adult-oriented intent amid evidence of primary sales to older demographics. Complementing Crazy Frog were secondary characters like Sweety the Chick, a flamboyant pink bird delivering high-pitched pop renditions, and , a fluffy whispering affectionate German-language tunes that appealed to sentimental markets. These figures followed a similar template: short, looped animations synced to downloadable content previews, broadcast in barrages to foster familiarity and urgency—"Text 'Crazy' to 12345 now!"—disguising recurring subscription fees as one-time downloads. The strategy's efficacy was evident in consumer surveys showing strong affinity among children, with over a third reporting fondness for the spots, though it simultaneously fueled backlash for perceived annoyance, earning Crazy Frog the title of Britain's most irritating TV ad of . Beyond television, Jamba! extended character exploitation into digital and physical merchandise, licensing for plush toys, apparel, and mobile games to prolong cultural penetration and diversify revenue, though core sales remained tied to SMS-driven content delivery. This character-centric model prioritized psychological stickiness over subtlety, leveraging irritation as a proxy for memorability in an era of nascent mobile personalization, but it invited ASA interventions requiring clearer billing disclosures and ad restrictions targeting minors.

Controversies and Criticisms

Billing and Subscription Practices

Jamba! primarily utilized premium short message service () billing for its and mobile content offerings, where consumers sent text messages to to access content, resulting in charges added directly to their bills by carriers. This method facilitated a subscription model that delivered recurring content, such as weekly ringtones or videos, at rates typically ranging from $5 to $10 per week or $20 to $30 per month, depending on the market and carrier agreements. Advertisements often presented the initial purchase as a one-time fee for a single , with or post-purchase confirmation messages disclosing the ongoing subscription, which many users overlooked or failed to receive clearly. The subscription practices drew widespread criticism for inadequate transparency, particularly in targeting younger demographics through television and online ads featuring characters like Crazy Frog. In the United States, a 2005 class-action lawsuit filed in San Diego accused Jamster (Jamba!'s U.S. brand) of false advertising after a customer's minor daughter incurred unexpected recurring charges following an SMS purchase advertised as a single ringtone acquisition. Similarly, in the United Kingdom, the Advertising Standards Authority (ASA) upheld 80 complaints in 2005, ruling that Jamba! advertisements misled consumers into believing they were buying a one-off ringtone for £3, when the action actually initiated a subscription service costing up to £12 weekly; the company was required to refund affected customers and clarify terms in future ads. Regulators noted that cancellation required specific SMS commands or calls to helplines, processes complicated by delayed billing cycles and lack of prominent unsubscribe options in initial confirmations. These practices contributed to inflated bills for thousands of users, with Jamba! reportedly generating an estimated £10 million from Crazy Frog-related subscriptions in the UK alone by late 2005, prompting to fine the company £40,000 for failing to ensure consumers understood the recurring nature of charges. agencies highlighted systemic issues in the premium ecosystem, where carriers shared revenue with content providers like Jamba!, incentivizing minimal barriers to enrollment but raising accountability gaps for unauthorized or unintended subscriptions. While Jamba! defended its model as compliant with carrier guidelines and requiring affirmative user action via , the prevalence of parental complaints—often involving minors racking up hundreds in charges—underscored deficiencies in consent verification and disclosure efficacy.

Consumer Complaints and Media Backlash

Consumers reported widespread issues with Jamster's subscription model, where advertisements for ringtones and implied one-time purchases but enrolled users in recurring weekly or monthly fees of $9.99 without clear disclosure. These charges, often appearing as "premium SMS" or third-party line items on phone bills, led to complaints of unauthorized "cramming," with some consumers facing cumulative bills exceeding $75 for content they did not intend to subscribe to or even receive. The use of WAP billing technology exacerbated the problem by capturing phone numbers during interactions and initiating charges without explicit consent or easy mechanisms. Particularly contentious were tactics targeting minors, such as TV ads featuring characters like the that promised "free" ringtones, only to trigger paid subscriptions upon texting a . A 2005 class-action lawsuit in alleged that Jamster's promotions deceived children and teens, resulting in unexpected charges that parents discovered on bills, with one case involving a father's claim over his daughter's enrollment. Cancellation processes were reported as opaque, requiring multiple contacts or navigating automated systems, further fueling consumer frustration documented in forums and regulatory filings. Media coverage amplified these grievances, portraying Jamster as emblematic of predatory practices amid the boom of the mid-2000s. Outlets highlighted the discrepancy between flashy, repetitive TV ads and the hidden subscription traps, with terms like "" applied in reporting on FTC probes into phony security alerts that tricked users into anti-virus subscriptions. In the UK, where Jamba! operated internationally, nearly 300 complaints to the Advertising Standards Authority in 2005 prompted rebukes for failing to clarify recurring costs, leading to ad restrictions and fines equivalent to £40,000 against billing partners. This scrutiny contributed to a broader backlash against the industry, with regulators citing Jamster's "careless disregard" for consumer protections in decisions that upheld complaints.

Investigations and Settlements

In 2008, Jamba! GmbH was among the mobile content providers scrutinized in an EU-wide "sweep" coordinated by authorities across 27 member states, targeting websites offering ringtones, wallpapers, and subscriptions for violations of directives on unfair commercial practices, contracts, and electronic . The investigation focused on deceptive , such as unsubstantiated claims of "free" content leading to hidden recurring fees, lack of clear total costs, and insufficient trader identification, with 80% of examined sites found non-compliant overall. While the sweep resulted in administrative actions, commitments to alter practices, and some national fines on other operators, no specific monetary penalties were publicly imposed on Jamba! GmbH, though it contributed to broader industry commitments for transparent billing disclosures. In , groups and media highlighted Jamba!'s model of automatically enrolling users in subscriptions upon purchasing a single via without explicit prior consent or clear cost warnings, drawing political scrutiny in 2005 parliamentary hearings on . Jamba! defended its practices as featuring fixed prices prominently advertised, distinguishing itself from premium-rate hotline billing ruled unlawful by the , and no formal fines or settlements ensued from these probes. Across and the , Jamba!-affiliated brands like Jamster faced class-action lawsuits alleging misleading television and online ads that tricked consumers, especially minors, into unauthorized subscriptions through ambiguous "send now" prompts, violating unfair competition and warranty laws. , which acquired Jamba! in 2006, disclosed ongoing litigation in SEC filings, including suits against subsidiaries Jamba! GmbH and Jamster International SARL, but aggregate settlement details specific to Jamba! were not itemized publicly. In the United States, the Jamster brand—operated post-VeriSign divestiture by Jesta Digital—settled charges in 2013 for "cramming" unauthorized recurring fees onto mobile bills via deceptive promotions disguised as free games or antivirus alerts, agreeing to $1.2 million in civil penalties and consumer refunds totaling over $900,000. The FTC emphasized failures in clear disclosure of subscription terms and ease of cancellation, practices echoing earlier Jamba! criticisms in .

Industry-Wide Reforms Triggered

The aggressive subscription billing practices employed by Jamba! and similar providers in the sector drew intense regulatory scrutiny, culminating in measures that extended beyond individual companies to reshape mobile content distribution. In the , following Advertising Standards Authority (ASA) rulings in 2005 against Jamster (Jamba!'s brand) for misleading advertisements that appealed to minors and obscured subscription terms, the mobile industry adopted self-regulatory guidelines mandating prominent disclosure of service charges, billing frequency, and cancellation instructions in all promotional materials. These changes were prompted by over 300 upheld consumer complaints regarding unauthorized recurring charges, signaling a broader push for transparency in premium services. In the , the cumulative scandals involving deceptive ringtone sites—many mirroring Jamba!'s tactics of hidden subscriptions via premium-rate numbers—led to a coordinated action by national authorities, resulting in the closure or modification of over 200 websites and the imposition of stricter verification requirements for age-restricted content. This initiative targeted "scam" operations that billed users without clear consent, enforcing uniform standards across member states for explicit opt-in mechanisms and prohibiting misleading premium service promotions, which effectively curbed the unchecked proliferation of such content. In the United States, while direct FTC action against !/Jamster came later in 2013 with a $1.2 million settlement for cramming charges via deceptive "" tactics on mobile browsers, the earlier wave of class-action lawsuits alleging fraudulent billing—such as a 2005 suit claiming Jamster induced minors into unintended subscriptions—amplified calls for carrier accountability. These cases contributed to FTC and FCC probes into "mobile cramming," where third-party content providers exploited carrier billing systems, leading to industry-wide mandates for line-item transparency on bills and simplified processes by the early 2010s. Carriers like faced multimillion-dollar settlements, such as the 2014 $105 million FTC agreement, which enforced verified third-party charge authorization and retroactive refunds, setting precedents that diminished reliance on opaque subscription models across mobile entertainment.

Decline and Legacy

Factors Leading to Decline

Several factors contributed to Jamba's decline beginning in the mid-2000s and accelerating through the 2010s, including heightened competition from larger quick-service chains that expanded into smoothies, eroding Jamba's market differentiation. Companies such as and introduced blended fruit drinks, reducing the novelty of Jamba's core offerings and capturing share in the healthy beverage segment. Seasonal demand fluctuations exacerbated sales volatility, with Jamba's fruit-based products performing strongly in summer but struggling during fall and winter months, particularly in like where cooler weather suppressed traffic. Rising operational costs further pressured profitability, as ingredient expenses for concentrates and frozen remained high, yielding thin margins that limited price competitiveness against alternatives or home blending. Labor cost increases halved restaurant-level margins to 6.8% in some periods, compounded by investments in and elevated store expenses. Shifting consumer perceptions of also undermined demand, as juices faced scrutiny for high content comparable to sodas, prompting to rebrand by dropping "" in 2019 to emphasize smoothies and amid declining juice sales. The transition to a franchise-heavy model introduced additional challenges, with post-franchising declines and net losses linked to overexpansion into unprofitable locations and costly buybacks of underperforming franchised stores. Economic pressures, including reduced disposable income during downturns, curtailed on premium treats like smoothies. Store closures reflected these issues, driven by high rents, depressed foot traffic, and franchisee financial strain, as seen in a 2023 shutdown and a 2025 Chapter 11 filing by franchisee Valley Juice LLC affecting multiple locations.

Long-Term Impact on Mobile Entertainment

The controversies involving Jamba! (operating as Jamster in many markets) exposed systemic flaws in early mobile content monetization via premium services, catalyzing regulatory reforms that enhanced consumer protections across the industry. In the United States, the (FTC) pursued enforcement actions against Jamster for misleading advertisements that obscured subscription costs and renewal terms, resulting in a 2006 settlement requiring clear disclosures and restitution to affected consumers exceeding $1 million. Similar probes in , including by the UK's Office of Communications (), led to fines and mandates for verifiable billing consent, influencing the EU's 2009 Consumer Rights Directive provisions on transparency. These interventions established precedents for truth-in-advertising in mobile marketing, compelling carriers like Verizon and to adopt standardized protocols and pre-billing notifications by 2008. The backlash against Jamster's opaque practices accelerated the obsolescence of SMS- and WAP-based entertainment models, which dominated from 2000 to 2007 but generated over $1 billion annually in ringtones and wallpapers before declining sharply. By highlighting risks—such as unauthorized recurring charges averaging €10-20 monthly per subscriber—Jamba!'s scandals pressured the industry toward app store ecosystems launched in 2008 (iOS App Store) and 2009 (), where in-app purchases supplanted premium SMS with centralized, auditable billing systems reducing chargeback rates by up to 90% compared to pre-smartphone eras. This shift prioritized developer-vetted content and refund mechanisms, though it introduced platform fees (typically 30%) that reshaped revenue models for mobile games and media. Long-term, Jamba!'s legacy fostered heightened consumer skepticism toward unsolicited mobile promotions, contributing to a 40% drop in premium content adoption post-2010 as users favored free or ad-supported alternatives. Industry-wide, it spurred self-regulation via bodies like the Mobile Entertainment Forum, which by 2012 promulgated guidelines for ethical microtransactions, influencing modern designs in apps like and to emphasize upfront cost visibility. However, persistent issues with in-app subscriptions echo early pitfalls, as evidenced by ongoing FTC scrutiny of mobile gaming firms, underscoring incomplete resolution of billing transparency challenges.
