Rockline was a nationally syndicated radio interview program hosted by Bob Coburn that was broadcast live via satellite every Monday and Wednesday night from 8:30pm-10pm PT to radio stations in the United States and Canada. Founded in 1981, it was considered to be the longest running, uninterrupted program in rock history. The main guests interviewed on the program were various musical artists of the rock genre, including both active rock artists (on Mondays) and classic rock artists (on Wednesdays). The primary feature of the program was the ability for listeners to call live and ask questions to the guests. Several of the shows were also live performances.
