Wednesday was a ratings whopper for a pair of cablers. The premiere of Black. White. drew four million total viewers for FX (nearly triple the net's previous best for an unscripted series), while the Project Runway finale (tailing Black. White. in the 10 pm hour with 3.4 million viewers) became Bravo's highest-rated program ever.... Speaking of Bravo, it has inked a deal worth $15 million-plus to begin airing HBO's Six Feet Under this fall.
