At the time of the station's launch (a time when "real oldies" was experiencing a certain degree of revival on the AM dial), the True Oldies Channel featured only music from 1955 to 1969 with less than ten percent from 1970 to 1973 (for example "Tears of a Clown" and "Burning Love"). The format was 60% 1964 to 1969 (the post-British Invasion era) and 40% 1955 to 1963 (the pre-British Invasion rock and roll/doo-wop era). It was the network's original mission to avoid the trends of other oldies outlets and remain committed to the music produced from the beginning of the rock-and-roll era to the disco era (1955 to 1979), purposefully drawing the line of what they would (originally) never air at 1980. By 2005, oldies from the early 1970s were added in moderation, while the pre-1964 material was cut back slightly. In 2006, more late 1970s music was added and the pre-1964 songs were cut down to 2 or 3 per hour. In March 2008, the pre-1964 music was cut down to one song per hour during the day and twice an hour on overnights; and the hits from the late-1960s and early- to mid-1970s was played in equal amounts. A few 1980s cuts were also added.
