CBS Corporation is an American media conglomerate focused on broadcasting, publishing, billboards, and television production, with most of its operations in the United States. The President and CEO of the company is Leslie Moonves. Sumner Redstone, owner of National Amusements, is CBS's majority shareholder & serves as Chairman. The company's name came into being on December 31, 2005 and began trading on the NYSE on January 3, 2006. Until then, the corporation was known as Viacom, and is the legal successor to said company. A new company, keeping the Viacom name was spun off from CBS. CBS, not Viacom, retains control of the partial and total over-the-air television & radio broadcasting, TV production & distribution, publishing, pay-cable, recording, and outdoor advertising assets formerly owned by the larger company. However, National Amusements, through Redstone, retains majority control of both firms. CBS has its headquarters in Midtown Manhattan, New York City.
