After his retirement, Marciano entered the world of television, first hosting a weekly boxing show on TV in 1961 and later appearing in the "Combat!" episode "Masquerade". For a brief period, he worked as a troubleshooting referee in wrestling (Marciano was a good wrestler in high school). He continued as a referee and boxing commentator in boxing matches for many years. He was also active in business as a partner and vice president of Papa Luigi Spaghetti Dens, a San Francisco-based franchise company formed by Joe Kearns and James Braly. He built a custom home at 641 NW 24 Street in Wilton Manors, Florida, a suburb of Fort Lauderdale. The house still stands as of 2018.
