Harper left WAKY at the end of January 1970 to return to Atlanta — to work in television, at
WTCG, rather than in radio. An article in
The Courier-Journal reported that Harper "told about a TV show, as yet unnamed, patterned after a Top 40 radio operation, designed to run twice a week." The program,
Now Explosion, ran from noon each Saturday until 2 a.m. Sunday and from noon each Sunday until 3 a.m. Monday. Harper and Bob Todd were the hosts. Later in 1970, a different version of the program,
The Now Explosion! was broadcast on
WPIX-TV in New York City. It premiered on June 20 with a 4:30-6 p.m. broadcast followed by a different episode that night from 11 o'clock to 2 a.m. Harper was described in an article in the
New York Daily News as "the off-camera announcer". The programs were recorded in Fort Lauderdale, Florida. == Other activities ==
