Roberts showed good judgment as “Tennessee Waltz” sold ten million copies worldwide.
Roberts also formed the "Korean Armed Forces Radio Network", with long-range signals reaching Japan, the Philippines, and Guam.
From 1956 until 1976 his racing show was broadcast across a three-state radio network of 7 to 14 stations in Pennsylvania, New York and New Jersey.
He also helped line up the television stations for a national TV network of his own and innovated closed-circuit boxing in hotel ballrooms and racetracks.
[10] In 1971 he launched Roberts Television International and introduced broadcast syndication of major sports and entertainment programming.
He purchased the rights to telecast Laurel Park's signature race, The Washington D.C. International Stakes.
In his three years at the track he introduced an advance-deposit wagering system allowing betting to be conducted over the telephone.
