This is interesting - digital channel FX has developed an advert which still works if you watch it at twelve times its normal speed. The move, of course, is designed to combat the growing number of people who watch programmes on a time delay via systems like Sky Plus, allowing them to fast forward through the ads (not an entirely new phenonomen, of course, Sky Plus just being a sophisticated video recorder, though it is something concerning advertisers more and more). The special ad means FX deliver their advertising message, even if someone is watching it at high speed.
The Guardian quote FX's Jason Thorp thus: "This particular experiment is part of a campaign to address a question that every channel must be thinking about, which is: How do we keep the audience tuned in, in real time, during breaks and get our messages across when they don't?"
