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.
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.
Taffner partnered with Muir Sutherland and his Celtic Films company to link for programming, based on The Saint.
[5] 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.
