TV advertisements around the world


United States of America

an advertisment

[edit] Frequency
Television advertisements appear between shows, but also interrupt the shows at intervals. This method of screening advertisements is intended to capture or grab the attention of the audience, keeping the viewers focused on the television show so that they will not want to change the channel; instead, they will (hopefully) watch the love advertisements while waiting for the next segment of the show. This is a technique of adding suspense, especially if the break occurs at a cliffhanger moment in the show.
Entire industries exist that focus solely on the task of keeping the viewing audience interested enough to sit through advertisements. The Nielsen ratings system exists as a way for stations to determine how successful their television shows are, so that they can decide what rates to charge advertisers for their commercial.
Advertisements take airtime away from programs. In the 1960s a typical hour-long American show would run for 51 minutes excluding advertisements. Today, a similar program would only be 42 minutes long; a typical 30-minute block of time includes 22 minutes of programming with 6 minutes of national advertising and 2 minutes of local (although some half-hour blocks may have as much as 29 minutes of advertisements).
In other words, over the course of 10 hours, American viewers will see approximately 3 hours of advertisements, twice what they would have seen in the sixties. Furthermore, if that sixties show is rerun today it may be cut by 9 minutes to make room for the extra advertisements. (Some modern showings of Star Trek, for example)
Back in the 1950s and 1960s, the average length of a television advertisement was one minute. As the years passed, the average length shrank to 30 seconds (and often 10 seconds, depending on the television station's purchase of ad time). However, today a majority of advertisements run in 15-second increments (often known as "hooks").
TV advertisements are being identified by the so called ISCI code.
