HBO Max is an American subscription video on demand service owned by Warner Bros. Discovery. Launched in the United States on May 27, 2020, the service is built around the libraries of HBO, Warner Bros., and their related brands. The service also carries first-run programming from the HBO pay television service, original programming under the "Max Originals" banner, and content acquired via third-party library deals and co-production agreements. The service succeeds both HBO Now—a previous HBO SVOD service, and HBO Go—the on-demand streaming platform for HBO pay television subscribers. In the U.S., HBO Now subscribers and HBO pay television subscribers were migrated to HBO Max at no additional charge, subject to availability and device support. HBO Max also supplanted the streaming component of DC Entertainment's DC Universe service, with its original series being migrated to HBO Max as Max Originals. The HBO Max service began to expand into international markets in 2021.
