Warner Bros. said Wednesday that Paratore suffered a heart attack Tuesday while bicycling in France.
Paratore was Warner Bros. Telepictures Productions president from 1992 to 2006 and executive vice president of Warner Bros. Domestic Television Distribution since 2002.
He built Telepictures Productions into a top producer of syndicated TV and a supplier of prime-time reality shows including "The Bachelor."
In 2006, Paratore founded TV production company paraMedia, which had an exclusive deal with the Warner Bros. Television Group. He was an executive producer of DeGeneres' talk show and the "TMZ" TV magazine.
He is survived by his wife, Jill Wickert, and his daughter, Martinique Paratore.
