It’s been months in the making, and today the Justice Department approved the merger of satellite radio networks XM and Sirius. Shareholders in both companies signed off on the merger in November, but it took the Justice Department until now to decide whether or not the new joint venture would be anti-competitive.

So why isn’t it anti-competitive? The government says the growth of mobile broadband devices would allow for more consumer choice. Gee, great, say Sirius and XM shareholders. We get what we want, though, because there will be even more ways to access entertainment on the fly. Oh, and the two companies still have to get approval from the FCC before you get those cool a la carte programming options.
