Viacom (2005–2019)

The second incarnation of Viacom Inc. ( or ; a portmanteau of Video & Audio Communications) was an American multinationalmass media and entertainmentconglomerate with interests primarily in film and television. It was split from the original Viacom on December 31, 2005, alongside the second incarnation of CBS Corporation. The controlling shareholder of both companies was National Amusements, a theater company headed by businessman Sumner Redstone. The split was structured so that the original Viacom changed its name to CBS Corporation and spun out its cable and film interests as a new Viacom.

The second Viacom operated Viacom Media Networks, through which it controlled approximately 170 networks and reached approximately 700 million subscribers in approximately 160 countries. Viacom's studio assets included Paramount Pictures, MTV Films, and Nickelodeon Animation Studio, as well as a 30% ownership stake in the Rainbow S.p.A. animation studio. CBS Corporation retained the over-the-air broadcasting, television production, pay television subscription service, and publishing assets, which were previously owned by the first Viacom. The second Viacom was the world's ninth-largest media company in terms of revenue and headquartered at One Astor Plaza in Midtown Manhattan, New York City.

Viacom announced its second merger with CBS Corporation on August 13, 2019. The merger was completed on December 4, resulting in the creation of ViacomCBS (later Paramount Global which would later merge with National Amusements and Skydance Media to form Paramount Skydance Corporation)
