Prime time or the peak time is the block of broadcast programming taking place during the middle of the evening for a television show. It is mostly targeted towards adults (and sometimes families). It is used by the major television networks to broadcast their season's nightly programming. The term prime time is often defined in terms of a fixed time period—for example (in the United States), from 8:00 p.m. to 11:00 p.m. (Eastern and Pacific Time) or 7:00 p.m. to 10:00 p.m
