In just under two weeks, Paramount Global will complete its merger with the smaller Skydance Media to form “ Paramount Skydance Corp.” — and bring a rollercoaster M&A ride to its conclusion. The FCC cleared the Skydance-Paramount deal Thursday, removing the last regulatory obstacle.

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