As the massive $110 billion mega-merger between Paramount Skydance and Warner Bros. Discovery prepares to cross the finish line next week, the newly combined media giant is already shaking up its leadership ranks and setting the stage for a new era in entertainment. In a major executive appointment announced today, Paramount CEO David Ellison revealed that former Mattel chief executive Ynon Kreiz is joining the company as co-CEO, effective upon the closing of the transaction.
Kreiz, who recently stepped down from his eight-year tenure leading toy and entertainment powerhouse Mattel, will officially start his new role at Paramount on October 5. While Ellison will remain chairman and chief executive officer of the overarching enterprise, Kreiz will step in as co-CEO and also secure a seat on the corporate board of directors. During his time at Mattel, Kreiz earned widespread industry acclaim for steering a sweeping business transformation and executing a brand-centric intellectual property strategy that successfully turned classic toy lines into major cinematic and cultural properties.
The high-profile executive addition brings a clear division of operational responsibilities to the newly formed media titan. Ellison is set to focus heavily on the company’s long-term corporate strategy, overarching vision, high-level talent relationships, strategic partnerships, cutting-edge technology initiatives, and capital allocation. Meanwhile, Kreiz will take the helm of day-to-day management and operational execution, providing the hands-on leadership required to merge two legacy Hollywood studios into a single, cohesive global enterprise.

Addressing the structural shift and the appointment of his new partner, Ellison emphasized the unique demands of steering a company of this magnitude. Bringing together Paramount and Warner Bros. Discovery to create a next-generation global media company is a transformational moment for our industry, Ellison noted in a statement released by the company. Leading it takes a rare combination of strategic vision, operational depth, and experience running a public company at the highest levels of media, Ellison added, noting that Kreiz brings all three of those crucial qualities to the table. In Ynon, Ellison said, I am adding a partner with strong leadership and the operating firepower this integration demands.
The adoption of a co-CEO leadership model is not entirely unprecedented in the modern streaming and entertainment landscape. Paramount’s decision to implement a dual-chief executive structure directly follows in the footsteps of streaming giant and primary competitor Netflix, which currently operates under the joint leadership of Ted Sarandos and Greg Peters. The shadow of Netflix looms large over the current media landscape, particularly given that Netflix was previously in line to merge with Warner Bros. Discovery earlier this year. That potential blockbuster pairing ultimately fell apart after months of speculation, clearing the path for Paramount’s aggressive new bid and the subsequent $110 billion agreement that is now on the verge of completion.
Beyond the headline-grabbing appointment of Kreiz, the impending merger is also triggering significant leadership shifts across the combined company’s digital and television divisions. Cindy Holland, the current head of Paramount+, is exiting the company ahead of the formal completion of the merger. In her place, Casey Bloys, the highly regarded head of HBO, is set to take the reins of streaming for the newly combined corporate entity, consolidating prestige television and broad subscription video-on-demand services under a single unified leadership umbrella.
These executive shufflings arrive alongside other high-profile departures within the broader corporate ecosystem. Industry watchers have confirmed additional adjustments to the network and digital portfolios as the corporate machinery prepares to integrate the vast assets of both historical studios. As the closing date approaches next week, the newly combined Paramount Skydance and Warner Bros. Discovery is rapidly solidifying the leadership team tasked with navigating one of the largest and most complex corporate consolidations in the history of the entertainment industry.
