''This is the version for the What if? idea of the ViacomCBS/SPE merger. Click here to view the original.''Paramount Prime is an American video-on-demand subscription streaming service owned by ViacomCBS. The streaming service features content from Paramount, Nickelodeon, Star Trek, and CBS Entertainment Group; while excluding other ViacomCBS companies, such as MTV and Comedy Central, so to focus on "family-oriented" content.

It primarily distributes films produced by Paramount Pictures and television series produced by Paramount Television Studios and CBS Television Distribution in particular. The streaming service also serves as the American alternative of Paramount+, which is available outside the United States.

Similar to Disney+ and HBO Max, it also presents original film and series; while the original films are produced by Paramount.

Content
The service is centered around ViacomCBS' entertainment studios: Paramount Pictures, Paramount Animation, Paramount Television Studios, Nickelodeon Animation Studio, Nickelodeon Movies' computer-animated film library, and select content from CBS Entertainment, and select films from Columbia Pictures, TriStar Pictures, and CBS Films. The service will also not carry any content from Comedy Central, MTV, or VH1 due to their mature content; as Hulu will handle those networks. The service also omits any mature content from Paramount and CBS' part.

Content library
Paramount Prime will have content from Paramount, Nickelodeon, and CBS, as well as select television series from Paramount Television Studios and CBS Television Distribution, as well as select titles from Columbia Television. However, the entirety of Nickelodeon's live-action television series, its movie division's traditionally-animated and live-action films will be available on CBS All Access; making their fully computer-animated films and animated series exclusive to Paramount Prime, while content from its sister channel Nick Jr. will be available on Netflix.

Half of the Indiana Jones franchise is featured exclusively on the streaming service since Paramount retained the distribution rights to the first four films and television series The Young Indiana Jones Chronicles. This also included two of Peanuts' films Race for Your Life, Charlie Brown and Bon Voyage, Charlie Brown (and Don't Come Back!!), which were both distributed by Paramount as well. Unfortunately, Paramount's 2006 to 2012 library of the 14 films it has distributed for DreamWorks Animation is not available due to the distribution rights having been transferred to Universal Pictures since 2018. This also included the 1991 animated series Doug due to being a property of The Walt Disney Company since 1996, along with being available on Disney+.
