How is &#39;National Amusements&#39; allowed to own Paramount Global? As well as CBS, etc.? In light of U.S. v. Paramount?
<p>I know that 1948 was a long time ago, and that antitrust decisions/regulations/etc. seem to weaken over time, but....</p>
<p>The Paramount Global CBS Viacom Whatever conglomerate, majority-owned by National Amusements, Inc., is a company that integrates production of TV shows and movies with distribution of those shows and movies.....</p>
<p>In light of the ongoing writers' strike, should these conglomerates be broken up again?</p>

<h2>Markets change over time</h2>
<p>Most anti-trust/monopoly laws are framed in terms of market dominance.</p>
<p>In 1948, the only market for video was the cinema. That was an inherently local market; outside the big cities, customers literally had one and only one realistic option.</p>
<p>In 2023, the market for video is on multiple platforms, geographically unrestricted, largely independent of time, and probably includes non-video media. The market is bigger so what it takes to dominate the market is also bigger.</p>
