Originally launched as CBS All Access on October 28, 2014, the service was rebranded as Paramount+ on March 4, 2021, following the 2019 re-merger of CBS and Viacom. Paramount+ would also expand to international markets, starting with Latin America and the already existing Canadian service on the day of the service's rebranding, followed by the Nordic countries on March 25, and Australia a few months afterward.[3][4]
