Why should the digital bring about ideas of progress in the theatre arts? This question opens up a rich seam of provocative and original thinking about the uses of new media in theatre, about new forms of cultural practice and artistic innovation, and about the widening purposes of the theatre's cultural project in a changing digital world. Through detailed case-studies on the work of key international theatre companies such as the Elevator Repair Service and The Mission Business, Bill Blake explores how the digital is providing new scope for how we think about the theatre, as well as how the theatre in turn is challenging how we might relate to the digital.
