With the Columbia record label out of ownership, Paley rebranded the network as the Columbia Broadcasting System.[3] Under Paley's guidance, CBS would first become one of the largest radio networks in the United States, and eventually one of the Big Three American broadcast television networks. In 1974, CBS dropped its original full name and became known simply as CBS, Inc. The Westinghouse Electric Corporation acquired the network in 1995, renaming its corporate entity CBS Broadcasting, Inc. two years later, and eventually adopted the name of the company it had acquired to become CBS Corporation.
