James John Lange was an American game show host and disc jockey. He was known to listeners in the San Francisco and Los Angeles radio markets with stints at several stations in both markets, racking up over 45 years on the air. Lange was also known to television viewers as the host of several game shows, including The Dating Game.

The Dating Game is an American television game show that first aired on December 20, 1965, and was the first of many shows created and packaged by Chuck Barris from the 1960s through the 1980s. ABC dropped the show on July 6, 1973, but it continued in syndication for another year (1973–1974) as The New Dating Game. The program was revived three additional times in syndication afterward, with the first from 1978 to 1980 as The All-New Dating Game, the second from 1986 to 1989, and the third from 1996 to 1999.
