TheAwl.com says it’s CBS, adding:
It’s mildly surprising that Fox is such a close challenger to CBS’ ivory crown. In the network’s infancy it was progressive in not only casting African Americans but also doing entire shows that were predominantly black. “In Living Color” had every Wayans ever, David Alan Grier, Jamie Foxx, Tommy Davidson and T’Keyah Crystal Keymáh. “Living Single” cast Kim Coles, Queen Latifah, Kim Fields, and Erika Alexander. Fox even gave Sinbad his own show.
Instead of putting a token minority on an otherwise white show, Fox was casting shows that were almost entirely devoid of white people.
Curiously though, the development of new such show casts trailed off about the time Fox won the rights to the NFL in 1993 (although they did run “The Bernie Mac” show from 2001 to 2006).
