Hello, FCC?

Can somebody explain to me what the hell is going on with the Comcast SportsNet that is now taking hold of the Bay Area? I’m no legal expert, but a TV provider owning actual TV stations strikes me as bad. There’s a reason why the Supreme Court broke up the classic Hollywod studio system in 1948. And now we have a TV cable provider branding and producing its own TV program, while denying other sports channels widespread distribution? I’m sure I don’t understand all the subleties here, but this looks troubling. As of today, I can still receive my Giants and A’s games on the familiar channels, but isn’t the next logical step that the Comcast SportsNet, which has the exclusive on tons of local programming that is of public interest, become exclusive to Comcast customers? And isn’t the FCC supposed to prevent this stuff?
