 A handful of radio affiliates, including WZTI in Milwaukee, Wisconsin were test-subjects for the new cloud based distribution created by Synchronicity before the nationwide reinstatement.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).
