The retirement of Arthur Godfrey in April 1972 marked the end of long-form programming on CBS radio; programming thereafter consisted of hourly news summaries and news features, known in the 1970s as Dimension, and commentaries, including the Spectrum series that evolved into the "Point/Counterpoint" feature on the television network's 60 Minutes and First Line Report, a news and analysis feature delivered by CBS correspondents. The network also continued to offer traditional radio programming through its nightly CBS Radio Mystery Theater during week.
