CBS Corporation is an American multinational media conglomerate with interests primarily in commercial broadcasting, publishing, and television production which was formed as the legal successor to the original Viacom on January 1, 2006. It is one of two companies which succeeded the original Viacom, alongside the present-day Viacom; both are controlled by National Amusements, a theater company largely owned by Sumner Redstone. The spin-off was structured so that CBS Corporation would be the legal successor to the old Viacom, with the new Viacom being an entirely new company.
CBS Corporation comprises the over-the-air television (CBS and The CW) broadcasting, television production and distribution, publishing, pay-cable, basic cable, and recording assets that were previously owned by old Viacom. It is currently the world's eighth largest entertainment company in terms of revenue, and is headquartered at the CBS Building in Midtown Manhattan, New York City.
Major subsidiaries include CBS Interactive, CBS Records, CBS Sports Network, CBS Television Distribution, CBS Television Studios, Westinghouse Licensing, Showtime Networks, Simon & Schuster, TV Guide, The CW, and Pop TV
