In the fourth year of the network's Black in America special, CNN will follow eight African-American entrepreneurs immersed in the predominantly young, white, male world of Silicon Valley. The previews alone have people talking about the racial dynamics of the "promised land" for entrepreneurs — a Twitter debate broke out after a screening of the special when blogger-turned-investor Michael Arrington suggested that he would accept almost any black entrepreneur, regardless of merit.

"The New Promised Land: Inside Silicon Valley" airs Sunday night at 8 p.m. ET/PT.
