The Paramount CEO office of Chris McCarthy, George Cheeks and Brian Robbins is apt to look quite different once the Skydance-Paramount merger closes.

David Ellison plans sweeping changes at Paramount Global, including cuts at the company’s TV networks, billions of dollars more for streaming and an overhaul of top management, according to people familiar with his plans.

According to Bloomberg, Skydance Media founder and CEO David Ellison is expected to combine Paramount’s various television networks into a single business, effectively bringing the operational control of CBS, Showtime, MTV and related properties like Nickelodeon, CBS Sports, VH1, BET, TV Land, Pop TV, Channel 5 and Network 10 under a single leader.
