Morning drive time and afternoon drive time are two daypart equivalents to television prime time for radio broadcasting. They consist of the periods where the number of listeners is highest and, thus, commercial radio can charge the most for advertising. Drive times coincide with rush hours.
Mainstream stations employ high-status presenters for drive time shows. Examples include BBC Radio 1 who have Nick Grimshaw (on air in the morning) and Greg James (on air in the evening), and BBC Radio 2 who have Chris Evans (on air in the morning) and Simon Mayo (on air in the evening). In the United States, popular national hosts who are associated with morning drive include Howard Stern, Ryan Seacrest and Don Imus, while Sean Hannity is associated with afternoon drive on the East Coast.
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. For talk radio stations, drive time is characterized by regular news updates, as well as extremely frequent updates on traffic and weather forecasts to help commuters get to and from work. Primary news radio stations are almost always local during this time period.
Variations by country
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. In circumstances where the phrase drive time may be ambiguous, the term home time may also be used for afternoon drive.
In the United States drive time consists of the morning hours when listeners wake up, get ready, and head to work or school, and the afternoon hours when they are heading home and before their evening meal. The exact times vary: morning drive times typically include 6–10 am; afternoon drive times typically include 3–7 pm In the United States, these are the time slots as defined by Nielsen Audio for audience measurement.
Multiple time zones
Depending on the station, morning drive can start as early as 5 am local time, although rarely any earlier. Because the contiguous United States spans four time zones, what constitutes drive time on one coast does not broadcast in drive time on the other, which can cause issues for nationally syndicated programs; this is not as much of an issue in morning drive, which usually incorporates a tape delay to air at the same time in all time zones, as it is for afternoon drive. However this effectively means that morning shows are heavily New York or East Coast-centric to allow time-shifting in all time zones, with some Central time zone shows making some additional headway. For all intents and purposes though, morning shows originating west of the Rockies must additionally plan to be mid-morning offerings for the rest of the country and adjust accordingly to be office-appropriate for those stations which take the shows in the east.
National satellite networks typically air their morning drive programs from 6–11 am Eastern Time, with heavy repetition. This is not an issue in the United Kingdom or New Zealand, where the entire country is in the same time zone. In Australia, there is a two hour time zone difference between the eastern and western coasts; and three time zones. Although Canada also spans several time zones, most of its drive time programs are local and are thus unaffected by these problems.
