CBS has been showing ads the last couple of days that are touting a new era for the company and calling it the "CBS Coprporation." What's that you say? Wasn't there already a "CBS Corporation?" Yes and no. Before CBS was bought by Westinghouse, and then later absorbed into Viacom, it was known as CBS Inc. This edition, which includes the television network, the owned & operated affiliates, and the Infinity radio network (which will go back to the name "CBS Radio"), officially broke off from Viacom today, and will be traded separately on the New York Stock Exchange. Viacom will still own the cable networks that it brought with them when they bought CBS a few years ago (MTV, VH1, Nickelodeon, etc.) Les Moonves will be the CEO of the new CBS Corp.
