Family Feud is a popular American television game show where two families compete to guess the most popular answers to survey questions. The show first aired in 1976 and has since been adapted and broadcast in numerous countries worldwide.
It is likely that the Family Feud logo was created using Clarendon Bold, a slab serif font developed by Hermann Eidenbenz in 1953, featuring all-caps letters except for the "y". This commercial font can be found with more information here.
