A dozen U.S. states have filed a lawsuit to block the proposed $110 billion merger between Warner Bros. Discovery and Paramount, asserting that the consolidation would stifle competition, increase consumer prices, and reduce content availability. California is leading the coalition of attorneys general in this legal challenge.

California Attorney General Rob Bonta stated that the merger would harm "audiences on every sofa and movie theater seat in the US." The lawsuit contends that the combination would result in higher prices, lower quality, and less content for both film and television. The states argue this would negatively impact movie theaters, basic cable distributors, and ultimately, consumers.

The proposed deal aims to merge two of Hollywood's major entertainment companies, creating a new entity that would control a significant portion of the major film release market. Together with Disney, Universal, and Sony, just four conglomerates would hold 86% of that market. The lawsuit specifically targets three areas: major cinema releases, blockbuster films, and cable television channels, arguing that the loss of competition between Warner Bros. Discovery and Paramount would weaken the bargaining power of movie theaters and television networks.

The coalition has requested that the companies halt the transaction pending judicial review and has threatened to seek a temporary restraining order if they do not comply. The Department of Justice had previously approved the merger in June.

Supporters of the merger argue that the traditional media landscape is facing significant challenges, including declining cable TV viewership and pressure from streaming services and tech giants. They maintain that increased scale is an economic necessity for survival.

Paramount has described the lawsuit as "fundamentally flawed" and "wrong," vowing to "vigorously defend the transaction." The company stated that delaying the merger would harm entertainment workers who have been affected by industry disruptions in recent years.
