BritBox is a subscription streaming service for British television, jointly launched by ITV and the BBC. With BritBox, viewers can stream programming from the BBC, ITV, Channel 4, and Channel 5. BritBox airs older content from the BBC and ITV to avoid competing with ITVX (formerly ITV Hub) and BBC iPlayer. It is available to viewers in the United Kingdom, Canada, and the United States, who can watch BritBox content on their phones, tablets, computers, Chromecast, Apple TV, or Roku..
