Drive time is the daypart analog to prime time for radio broadcasting. It consists of the morning hours when listeners wake up, get ready, and/or head to work or school, and the afternoon hours when they are heading home and before their evening meal. These are the periods where the number of listeners is highest and, thus, commercial radio can charge the most for advertising. Drive times coincide with rush hour.

The exact times vary: morning drive-times typically include 6-10 a.m.; afternoon drive-times typically include 3-7 p.m. In the United States, these are the time slots as defined by Arbitron for audience measurement. 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. This is not an issue in the United Kingdom or New Zealand, where the entire country is in the same time zone. Although Canada also spans several time zones, most of its drive time programs are local and are thus unaffected by these problems.

William Thomas "Tommy" Emmanuel AM (born 31 May 1955) is an Australian guitarist and occasional singer, best known for his complex fingerstyle technique, energetic performances and the use of percussive effects on the guitar. In the May 2008 and 2010 issues of Guitar Player Magazine, he was named as "Best Acoustic Guitarist" in their readers' poll. In June 2010 Emmanuel was appointed a Member of the Order of Australia (AM).

Emmanuel was born in Australia in 1955. He received his first guitar in 1959 at age four, being taught by his mother to accompany her playing lap steel guitar. At the age of 7 he heard Chet Atkins on the radio. He vividly remembers this moment and says it greatly inspired him.

By the age of 6, in 1961, he was a working professional musician. Recognizing the musical talents of Tommy and his brother Phil, their father created a family band, sold the family home and took his family on the road. With the family living in two station wagons, much of Emmanuel’s childhood was spent touring Australia with his family, playing rhythm guitar, and rarely going to school. The family found it difficult living on the road; they were poor but never hungry, never settling in one place. His father would often drive ahead, organize interviews, advertising and finding the local music shop where they'd have an impromptu concert the next day. Eventually the New South Wales Department of Education insisted that the Emmanuel children needed to go to school regularly.
