In 1948, the Supreme Court ruled that five studios had monopolized the American film industry. Paramount, Warner Bros., MGM, RKO, and Fox owned the theaters that showed their own movies.
The court ordered them to sell.
For the next 72 years, the Paramount Consent Decrees kept the studios apart.
In August 2020, a federal judge terminated the decrees. The reasoning was that the market had changed beyond recognition.
Streaming had replaced theaters as the primary distribution channel. The studios were no longer dangerous monopolists. They were struggling incumbents.
Six years later, Paramount and Warner Bros. are merging. The deal is worth $111 billion including debt. The Justice Department approved it on June 12, 2026.
Two of the five studios that the Supreme Court forced apart are coming back together voluntarily. Not because they are too powerful, but because they are too weak to survive alone.
It’s a familiar story. Regulation is often designed to solve a specific market structure problem (monopoly power, natural monopoly characteristics, or high barriers to entry).
Over time, technology, globalization, new business models, and substitute products can eliminate the original source of market power. Regulations that once made sense may then become unnecessary, counterproductive, or even protective of incumbents.
In the case of the studios, massive changes in the video and movie business make older restrictions unnecessary.
Television was an alternative to “going to the movies, and therefore a threat. But studios discovered:
TV licensing created new revenue
Old film libraries became valuable assets
Syndication emerged as a lucrative business.
The additional changes in distribution (cable TV, home video, streaming) likewise emphasized the role of content ownership and creation for studios, even as new distributors emerged to capture value.
Among the new issues with streaming is the importance of distribution versus “discovery,” as “scarcity value” migrates.
Frequently, the substitute products and competitors come from “outside” an industry’s chosen domain.
Perhaps the classic example is railroads believing they were in the trains business, when they were actually in the transportation business. The substitutes did not come from inside the “railroad” business but from outside.
Each major distribution innovation created new winners, weakened existing gatekeepers, and shifted where revenue accumulated:
broadcast television
cable television
home video
DVD
streaming.
The point is that “where” monopoly danger exists will shift with time. And so must the regulatory concern. Emerging industries might need one pattern. Declining industries virtually always need another: preventing concentration early; encouraging it in the industry decline phase.
