In broadcasting, continuity or presentation (or station break in the U.S. and Canada) is announcements, messages and graphics played by the broadcaster between specific programmes. It typically includes programme schedules, announcement of the programme immediately following and trailers or descriptions of forthcoming programmes. Continuity can be spoken by an announcer or displayed in text over graphics. On television continuity generally coincides with a display of the broadcaster's logo or ident. Advertisements are generally not considered part of continuity because they are advertising another company.

A continuity announcer is a broadcaster whose voice (and, in some cases, face) appears between radio or television programmes to give programme information. Continuity announcers tell viewers and listeners which channel they are watching or listening to at the moment (or which station they are tuned to), what they are about to see (or hear), and what they could be watching (or listening to) if they changed to a different channel operated by the broadcaster. At the end of programmes, they may read out information about the previous programme, for example who presented and produced it, relay information or merchandise relating to the show, or to provide details of organisations who may offer support in relation to a storyline or issue raised in the programme. Continuity announcers may also play music during intervals and give details of programmes later in the day. If there is a breakdown, they make any necessary announcements and often play music for its duration.

Television continuity announcements typically take one of two forms:

Currently, the following European television channels use in-vision announcers:

With most radio stations now broadcasting only music, few networks retain continuity announcers.^{[citation needed]} Exceptions include talk stations such as National Public Radio in the United States, BBC Radio 4 and in the UK and SR P1 in Sweden. In the case of Radio 4 they also read the shipping forecasts and gale warnings. Many also serve as newsreaders.

In Canada, CBC Television used in-vision announcers to 'host' primetime programming from 2001 to 2006. As the credits rolled, the announcer would describe upcoming episodes of the series, then introduce the next program at the top of the hour. The evening's host changed daily. Usually, the host was appearing in a major upcoming program the same week, giving the appearance that the host is promoting not only the next program in the evening but his or her own upcoming show. Sometimes CBC Radio newscasters or program hosts would appear as the evening TV hosts. The initiative, sometimes known as "Hosted Prime", only covered the CBC's core evening block (8:00 to 10:00 p.m. local) as opposed to programs in the 7:00 hour, and would not normally appear during the summer.

CBC Radio One has used continuity announcers in recent years. Originally, a number of staff announcers shared the duties; however, in 2004, the service began employing actress Shauna MacDonald as its primary continuity announcer. Her identity remained a secret for more than a year, leading her to be dubbed "Promo Girl". MacDonald has since been replaced by Jeremy Harris, serving in a similar capacity for both Radio One and Radio 2.

Omni Television in Toronto has used in-vision continuity announcers for the past 10 years or so. These "interstitial" segments fill in the time left in programming due to the different break structure of American TV programming, that cannot be filled by commercials in Canada due to Canadian broadcast regulations regarding the number of minutes of commercials allowable per hour. The segments range from 30 seconds to 2 minutes, and in addition to announcing the station and the programs coming up, the announcers will talk about other programming, station contests, quirky news or celebrity gossip.
