ViacomCBS is playing the tonnage game with CBS All Access, paving the way for the launch of a renamed and bulked-up version of the direct-to-consumer streaming service in early 2021.

CBS All Access is adding 70 shows - representing more than 3,500 episodes in all - from legacy Viacom cable networks including BET, Comedy Central, MTV and Nickelodeon. The additional programming boosts CBS All Access' title count to more than 20,000 TV episodes and movies, and ViacomCBS plans to up that to over 30,000 by the time it relaunches the service next year.

`It's the first big step to transform All Access into the super-service we've been talking about,` said Marc DeBevoise, president/CEO of ViacomCBS Digital and ViacomCBS's chief digital officer.

The new content, to be available starting Thursday, includes all past seasons of Nick's `SpongeBob SquarePants` and all seasons of `Avatar: The Last Airbender` and `Rugrats`; all seasons of Comedy Central's `Chappelle's Show` and six prior seasons of `Reno 911!`; BET's `Real Husbands of Hollywood` (all seasons) and all prior seasons of `Single Ladies`; all seasons of MTV's `Laguna Beach` and `Snooki & Jwoww,` plus prior seasons of `Teen Mom 2,` `Jersey Show: Family Vacation` and `MTV Floribama Shore`; and prior seasons of VH1's `RuPaul's Drag Race.`

In addition, CBS All Access in 2021 plans to premiere a new original kids' series, `Kamp Koral,` the first spinoff from Nick's `SpongeBob SquarePants.` And, as previously announced, CBS All Access will also be the exclusive home to `The SpongeBob Movie: Sponge on the Run` in early 2021.

Outside the U.S., versions of CBS All Access have launched in Canada and Australia (where it's called 10 All Access) with different pricing and content lineups.
