Cablevision filed with the SEC to sell off its Voom satellite business and three cable networks, a move that the New York Post says "could mark the beginning of the end of the company in its current form." The four properties are part of Rainbow Media Enterprises, which earlier this month had been the subject of spin-off rumors. Instead of spinning off the company, though, Cablevision will search for outright buyers. On the news of the impending deal, shares of Cablevision rocketed more than 13%.

An interesting footnote to the deal: Cablevision has been locked in a dispute with Mayor Bloomberg over a planned stadium on the West Side of Manhattan for the New York Jets.
