In addition, most general interest or movie-based pay services do not adhere to the common top and bottom of the hour scheduling of other cable channels and terrestrial broadcasters. As such, programs often air using either conventional scheduling or have airtimes in five-minute increments (for example, 7:05 a.m. or 4:40 p.m.); since such channels broadcast content without in-program break interruptions, this sometimes leads to extended or abbreviated breaks between programs, depending on when the previous program concludes and when the start time of the next program is. The only universal variation to this is prime time, where the main channel in each pay service's suite usually schedules films to start on the hour.
