Taffner was born on November 29, 1930, in New York. He began working as a mail delivery agent for the
William Morris Agency in 1952. Between 1955 and 1959, he served as an agent. He later worked at
Paramount's New York office until, in 1963, he left the company to form DLT Entertainment (formerly D.L. Taffner Ltd.), a production company that began offering American series to international broadcasters. In 1975, Taffner acquired from
Thames Television the rights to the adaptation of the British series
Man About the House (1973–1976), which was produced in the U.S as the title of ''
Three's Company. Starring John Ritter, Suzanne Somers and Joyce DeWitt, the sitcom became a hit, produced between 1976 and 1984. The series spawned two spin-offs: The Ropers and Three's a Crowd''. This second was actually the continuation of the original production, which at the time had already been canceled. Trying to rescue the success of ''Three's Company
, Taffner bought the adaptation rights to the British series Keep It in the Family (1980-1983) and produced Too Close for Comfort''. In 1987, D.L. Taffner, Ltd. acquired the exclusive rights to the Thames Television game show
Whose Baby? and would remake the show for an American audience. That year, D.L. Taffner partnered with Muir Sutherland and his
Celtic Films company to link for programming, based on
The Saint. That year, Don Taffner had hired former
Camelot Entertainment Sales employee Rick Levy to join the studio, in which he had served as president of sales and marketing. After a few failed attempts, Taffner co-produced the British sitcom
As Time Goes By in partnership with Theatre of Comedy Entertainment, and starring
Judi Dench. The television series had 9 seasons, produced between 1992 and 2002, returning with specials in 2005. ==Legacy==
