Paramount, home to one of Hollywood’s most storied movie studios as well as CBS and cable networks like Nickelodeon, has been discussing entering into exclusive talks with the media company Skydance for a potential deal, according to four people with knowledge of the discussions. Moving to exclusive talks would be a significant step forward in a process that has been shrouded in uncertainty for months.

Shari Redstone is getting one step closer to selling her media empire. Whether the two sides will agree to exclusivity remains to be seen, especially with other investors still pursuing Paramount. Apollo Global Management, an investment firm with more than $500 billion under management, has submitted an $11 billion offer to acquire the Paramount movie studio. Paramount’s board of directors, though, is seeking a deal for the entire company — including its cable channels and CBS — rather than pieces.
