Trailer show time

Trailers are often shown at prime times, when the biggest possible number of people will be watching television. This is because it gains access to a larger number of viewers, and so is more likely to gain new audiences this way. On BBC1, trailers for a big soap opera episode are shown very regularly in the lead up to the sheduled showing, especially before and after the program is on. This is because those who are most likely to watch the trailered episode will be watching the normal episodes too.
