NET was a Brazilian telecommunications company that offered services such as cable television, broadband internet and telephony. The company's NET TV service (cable TV) had around 5.4 million subscribers as of Q2 2012. NET also operated the broadband Internet service NET Vírtua, with over 9 million subscribers as of Q2 2019 and telephone over cable (under the NET Fone via Embratel name) with more than 2.5 million subscribers. It is owned by Mexican telecom giant América Móvil. On 11 July 2019, the NET brand was absorbed into the Claro brand, already used by América Móvil for its mobile business in Latin America. In early 2020, the NET brand was relaunched into the Claro NET brand, and was later discontinued in 2022.

In 2011, Claro, Embratel and NET announced the integration of their networks and services. In 2014, Anatel accepted the merger of the three companies, allowing them to use the same corporate name. In January 2015, Claro incorporated the companies Embratel and NET and became a publicly-held company, with the corporate name "Claro S/A", but maintaining the companies' brands.

In July 2019, NET ceased to be an independent brand and became part of Claro's portfolio, giving its name to services aimed at the residential segment.

NET's pay TV, telephony and broadband services were incorporated into Claro's portfolio, consolidating the brand's multi-service offering, which was born in Brazil and is now present in several countries. Stores, websites and applications were also updated to facilitate interaction.

NET's products and services aimed at small and medium-sized companies were consolidated into Embratel's portfolio.

Claro TV was integrated with NET in the pay TV service, thus creating a single service called "Claro NET HD". Later, on 26 May 2022, the service was renamed Claro TV+.

Antônio Dias Leite bought some of these companies and founded Multicanal on December 12, 1991. One of his priorities was to get them up and running, with the intention of selling them later. The first purchase was of a small operator in Campo Grande, Mato Grosso do Sul, with around 100 users; the purchase was valued at around US$200,000. At that time, he had assets in TV Alphaville, a company owned by Silvio Santos that operated in the interior of São Paulo, and 80% in the RPC cable TV company in Rio de Janeiro. Therefore, Antônio Leite avoided large centers where Canais Globo (Grupo Globo) and TVA (Grupo Abril) operated. In 1992 and 1993, the company bought seven more operators or operating licenses, of which 6 were in São Paulo and one in Goiás.

The company followed the same lines as the major pay TV companies in the USA, going against its competitors in the country by ceasing to produce and only working with signal distribution. By 1993, the company was already present in several strategic locations and was in talks with its two competitors. In a second negotiation, Globopar (owned by Organizações Globo) and the American company Ralph Partners II obtained 30% of the company. With the entry of the American company, these engineers convinced Brazilians to invest in fiber optic devices and coaxial cables, which were more modern at the time, subsequently obtaining a greater range of services. With this, NET São Paulo was founded as the first multi-operator company in the country.
