Paramount streaming shake-up: HBO’s Casey Bloys set to take over as Cindy Holland exits ahead of Warner Bros. mega merger

Paramount’s streaming business is about to enter a major new phase, and one of the biggest clues came from an unexpected executive departure. Cindy Holland, who has overseen Paramount’s streaming operations, is leaving the company just days before Paramount Skydance is expected to complete its acquisition of Warner Bros. Discovery. HBO chief Casey Bloys is now poised to take charge of the combined company’s streaming operations, putting one of Hollywood’s most closely watched television executives at the centre of a much larger streaming business. The change comes as Paramount prepares to combine its streaming assets with Warner Bros. Discovery’s HBO Max and other businesses.

Cindy Holland exits Paramount

Holland announced her departure in a memo to employees on September 29, saying it would be her final day at Paramount. She said she and Paramount CEO David Ellison had discussed her role and the future of the combined businesses. Holland wrote that Ellison was “optimising for HBO stability” as the company moved into its next phase, adding that she supported the decision.

Holland joined Ellison’s team in 2025 and became responsible for Paramount’s direct-to-consumer operations, including Paramount+ and Pluto TV. In her memo, she pointed to several developments during her tenure, including Paramount+ reaching a record subscriber level, improved retention and growth in engagement and revenue. She also highlighted the transformation of Pluto TV and the expansion of Paramount+ programming and live sports.

Casey Bloys could lead the combined streaming business

With Holland leaving, attention has shifted to Bloys. Bloys currently leads HBO and has been one of the key executives behind the network’s television strategy. He is expected to oversee streaming operations across the combined Paramount-Warner Bros. business once the merger closes.

The appointment would put HBO’s leadership at the centre of a streaming operation spanning Paramount+ and HBO Max, alongside a much larger library of films, television programmes and franchises. However, the change does not mean that HBO itself is disappearing. Holland’s departure is being described as part of the leadership structure being prepared for the combined company, with Ellison seeking continuity around HBO while reorganising the broader streaming operation.

Why the Paramount-Warner merger matters

The executive shake-up is happening against the backdrop of one of Hollywood’s biggest corporate deals. Paramount agreed to acquire Warner Bros. Discovery in a transaction valued at about $110 billion, bringing together major entertainment properties including HBO, Warner Bros., CNN, CBS, Paramount+ and Paramount’s film and television operations. The companies announced on September 30 that they expect the merger to close on October 6, subject to the remaining closing conditions.

The deal has already faced legal and regulatory scrutiny. Paramount and a group of US states reached a settlement in September that cleared a major obstacle to the transaction. Under the agreement, Paramount made commitments concerning US film production, theatrical releases and editorial independence at CBS and CNN.

What happens to Paramount+ and HBO Max?

For viewers, one of the biggest questions will be how the combined streaming business is eventually organised. Paramount+ and HBO Max currently operate as separate services with their own identities, libraries and subscriber bases. The merger creates the possibility of a much larger streaming catalogue under common ownership, but the precise consumer-facing structure will depend on decisions made by the new leadership.

Bloys' appointment is significant because HBO has built a reputation around premium scripted television, while Paramount+ has a different mix of entertainment, films, franchises and live sports. The combined business will therefore bring together different content strategies under one corporate structure.

A new chapter for Paramount

Holland's exit marks the end of a relatively short but important period for Paramount's streaming operation. Her own memo portrayed her tenure as a period of rebuilding and expansion, while the company now prepares for a much larger corporate combination. For Bloys, the expected move would represent a substantial expansion of responsibility. He will be dealing not only with HBO's existing operations but with a streaming portfolio that sits at the heart of Paramount's strategy following its Warner Bros. Discovery acquisition.

With the merger expected to close in October, the next major question is no longer whether these two media businesses will come together, but how their enormous collection of streaming services, studios and entertainment brands will work under the new structure.
