You knew this already didn't you? Bottom line:
At least 77 percent of the 2,150 guests who appeared on the four major Sunday shows in 2005-06 were men; at least 82 percent were white.
Media Matters has a graph. But one of the most popular Sunday morning shows - the Chris Matthews Show - bucks this trend. Yes, I'm a regular, but not as regular as I would be if they didn't have quotas for women and minorities (and gay doesn't count).
