Jenny the librarian has a useful posting summarising the rise and influence of videogames. I particularly liked the quote from Entertainment Weekly about how television displays American football. “Look at the NFL’s running scoreboard, ref-mounted cameras, and even sound effects: They’re all lifted from videogames. ‘When we started Fox Sports in 1994, I went out and got…every videogame I could,’ says Fox Sports Networks chairman David Hill. ‘What fascinated me was how videogames were so rich and multi-layered, while television was two-dimensional’.”
Ed Felten has a lucid explanation for us non-techies as to why there are unbreakable codes but no unbreakable digital rights management.
