ESPN3 is a streaming video website operated by ESPN. It is not provided on a network channel with any cable providers. ESPN3 is currently known as WatchESPN. The site does require a valid subscription to a cable service to view, however.
ESPN3 originally launched as ESPN360.com with mostly studio content. Over time, the content shifted to include more live sporting events with more basic content than the primary ESPN presentation. Sporting events on ESPN3 typically only contain the basic commentary and very little in-studio content. ESPN3 also provides some on-demand replays of recent sporting events that the ESPN family of channels has the rights to broadcast.
