In an unexpected move that could dramatically reshape the media and entertainment landscape, Warner Bros. Discovery CEO David Zaslav met with Paramount CEO Bob Bakish this week to discuss a potential mega-merger of the two companies.

Sources close to the negotiations tell Axios that the Tuesday meeting took place at Paramount’s New York headquarters in Times Square. The discussion centered around possible synergies and how the two entertainment giants could complement each other’s assets, including potentially combining their streaming services, Max (formerly HBO Max) and Paramount+, to create a more formidable competitor to Netflix and Disney+.

Details of the potential deal are still vague, but options include Warner Bros. Discovery acquiring Paramount outright or its parent company, National Amusements. People briefed on the talks say that Zaslav also met with Shari Redstone, National Amusements’ President, to explore strategies around bringing the entertainment empires together.

The timing of the merger conversation is especially notable given that Warner Bros. Discovery itself only just formally completed its long-in-the-works $43 billion merger between Discovery Inc. and the WarnerMedia assets spun off from AT&T. That deal created one of Hollywood’s largest content companies, housing major brands like HBO, Warner Bros. Pictures, TLC, HGTV, and more under one roof.

A Paramount pact would concentrate even more media power into this new Warner Bros. Discovery entity and shrink the number of Hollywood studios. It also raises significant questions around antitrust issues, though the FTC declined to comment when contacted about the merger reports.

Zaslav aims to rapidly transform Warner Bros. Discovery into an unrivaled force in the world of film, television, news, and streaming. The vision took clearer shape this week in talks with Paramount’s leadership, but it remains to be seen whether a deal will progress past this initial stage. If it does, it would undoubtedly send more shockwaves through the already turbulent media sector.
