Television has traditionally been a shared viewing experience. It has been shared among members of a household and shared across a community of viewers. We talk about the television audience, reflecting its roots in theatre and cinema. This conception was based on being a simultaneous relay of a remote event, which continues to characterise television as a cultural medium, although many of its programmes are now prerecorded and can be delivered by other means and watched at our convenience, which is more like the relationship of a reader to a book. We are increasingly viewing alone, asynchronously, but it seems there is still a fundamental psychological need to share that experience with others and feel a sense of social connection. It is surprising that it has taken so long to address this.
