For popular music-oriented stations, morning drive-time is typically dominated by the "morning zoo" genre of radio program, with the afternoon portion is often given over to music (often in commercial-free blocks, especially in markets with long commute times) and light entertainment features.
In the United Kingdom and Australia, the term drive time is used almost exclusively to refer to the peak evening period (most commonly 16:00–19:00); the term used for the period of peak morning listening is breakfast, akin to the phrase breakfast television used for morning TV shows.
Depending on the station, morning drive can start as early as 5 a.m. local time, although rarely any earlier.
National satellite networks typically air their morning drive programs from 6–11 a.m. Eastern Time, with heavy repetition.
This issue is mitigated somewhat in Canada and Mexico, where most drive time programs are local and are unaffected by these problems.
