After finally getting approval from the Federal Communications Commission, Skydance Media is just weeks away from completing its $8-billion merger with Paramount Global, leading to sweeping changes for some of the most iconic media brands.

Under the two-step deal, Skydance is set to acquire controlling shareholder Shari Redstone’s holding company National Amusements, which controls 77.4% of the Paramount Class A common stock outstanding and approximately 9.5% of the overall equity of the company, before merging with the Hollywood studio.

It's not clear what title Greenstein will hold once David Ellison's $8 billion deal to buy Paramount Global officially closes.
