WZAK

93.1 FM WZAK went on the air in Cleveland, Ohio in May 1963 with an Ethnic format and programming in 17 different languages.  Some of the original owners were also franchisees of MUZAK, a provider of background music for retail stores and other public places.  They incorporated that company's name into their radio stations call letters.  After a brief format change to Beautiful Music in 1980, WZAK flipped to Urban Contemporary and then shifted slightly to Urban AC in 2000.
