Who Actually Owned CBS Over the Decades
CBS has changed hands more times than most people realize. The network started as a radio operation and grew into one of the biggest television networks in America. But the ownership story is messy, complicated by corporate mergers, regulatory changes, and some pretty blunt financial moves. If you are digging into this, you will find that tracking down accurate records takes more than a quick search. I spent weeks pulling together a timeline of CBS ownership for a project a while back. The easy sources tell you about William S. Paley and Viacom, but the real picture involves a lot of intermediate steps that most articles skip over. Here is what actually happened, based on filings, press releases, and the occasional obscure SEC document. William S. Paley is the name everyone knows. He took control of the Columbia Broadcasting System in 1928 after his father incorporated the company. Paley was only twenty-five. He reorganized the network, bought time on stationWABC, and turned CBS from a failing radio outfit into a serious competitor to NBC. Under his leadership, CBS acquired stations across the country and signed talent like Fred Waring and Bing Crosby.
Paley stayed in charge through the radio era and into television. He ran the network until 1974 when he stepped down as chairman. His son, William S. Paley Jr., was passed over for leadership in favor of Leonard Goldenson's brother-in-law, Thomas F. Reilly. That decision caused a family feud that lasted decades and still shows up in legal documents.
The Columbia Broadcasting System Becomes CBS Inc.
In 1963, the company changed its name from Columbia Broadcasting System to CBS Inc. That was not just cosmetic. It reflected a broader corporate structure that included publishing and other ventures. The name change also coincided with Paley consolidating his power through a complex web of holding companies and voting stock arrangements. Most people do not realize that Paley's control relied heavily on a special class of stock that gave him disproportionate voting rights. That structure made it very difficult for anyone to challenge him from the outside. When Paley finally retired, he was succeeded by Richard S. Salant, who had been president of News Corp's American division. Salant was a newsman, not a corporate operator. He lasted only three years before being pushed out during the 1974 leadership shuffle. Thomas F. Reilly took over and ran CBS through most of the late seventies and early eighties.

The Sumner Redstone Era
Sumner Redstone entered the CBS picture through National Amusements, the theater chain his father built. National Amusements held a controlling stake in Viacom, which had been spun off from CBS in 1971. Redstone used that position to pressure CBS into a merger. The deal closed in 1999. CBS became a subsidiary of Viacom, and Redstone effectively controlled both companies through his voting shares in National Amusements. This was not a friendly takeover in the traditional sense. Redstone had been building his stake quietly for years. He acquired shares through National Amusements and used proxy fights to install his allies on the CBS board. The Federal Communications Commission reviewed the deal because it raised ownership concentration concerns. They approved it with conditions, mainly around allowing CBS to maintain its news division's editorial independence. I ran into a problem when I was trying to verify the exact date when Redstone's control became absolute. Some sources say 1999 when the merger closed. Others point to 2000 when he became chairman of both companies. The truth is that his influence grew gradually. He gained board seats in 1998, pushed through the merger in 1999, and consolidated executive control in 2000. I ended up citing all three dates and explaining the progression rather than picking one. That is usually the honest way to handle this topic.
The 2006 Split
Viacom and CBS merged in 1999. They split again in 2006. The split happened because shareholders wanted to unlock value. The combined company was huge but inefficient. Viacom owned Nickelodeon, MTV, and Paramount Pictures. CBS owned the television network and CBS Studios. Keeping them together created conflicts between the cable channels and the broadcast network. The new Viacom kept the cable assets. The old CBS became a standalone broadcast company again. Redstone remained chairman of both entities through National Amusements. That arrangement lasted until his health declined in the mid-2010s. There was a bitter custody battle between his daughter Shari and his son Brent over who would control National Amusements and therefore both Viacom and CBS. The courts eventually sided with Shari.
The 2019 Merger and Today
In 2019, Viacom and CBS merged again. This time the deal was structured differently. The new company kept the ViacomCBS name, later changed to Paramount Global. Bob Bakish ran the combined organization. The merger was driven by the same logic as the original split: streaming competition required scale. Netflix and Disney were investing heavily in content. A smaller Viacom or a smaller CBS could not compete alone. The current ownership structure is more complex than earlier eras. Paramount Global is a publicly traded company. National Amusements still holds a controlling stake through super-voting shares. That means the Redstone family still has decisive influence despite Sumner Redstone being incapacitated and Shari Redstone managing the holdings. Individual shareholders own the rest, and institutional investors like Vanguard and BlackRock hold significant blocks.
Common Mistakes People Make
Most timelines get the 1971 spinoff wrong. Viacom was created when CBS wanted to sell its television station group without losing control of the network. The FCC at the time had rules about owning broadcast stations and cable networks. CBS spun off Viacom as a separate company to comply. That is the opposite of what many sources claim. They say Viacom was created to enter the cable business, which is true but misses the regulatory motivation. Another frequent error is treating the 1999 and 2006 transactions as simple acquisitions. They were not. Both involved complex debt structures, tax considerations, and regulatory approvals. The 1999 deal was financed largely with debt that Viacom had to service for years. That debt burden constrained both companies' ability to invest in content during the early 2000s. If you want accurate ownership records, start with SEC filings. Form 4 statements show insider transactions. Proxy statements reveal board control arrangements. Press releases from the companies themselves are useful but often promotional. Cross-reference everything. The ownership history of CBS is not a straight line. It is a series of corporate maneuvers that reflect the changing media landscape, FCC regulations, and the personal ambitions of a few powerful individuals.
I found that the most reliable single source is the CBS annual reports archived through the SEC's EDGAR database. They go back to the 1970s and contain ownership disclosures that secondary sources often miss or simplify. It is tedious reading, but it is accurate. The alternative is piecing together information from entertainment trade publications, which can be inconsistent on dates and transaction details.
