What's the best way to encourage young people to vote? There's no definitive answer, but switching off a TV channel is one of the more unusual ideas we've heard about. For the UK's General Election on May 7th, Channel 4 says it will "shut down" E4 from 7am and instead show a fictional character called Darren. As promotional ads reveal, the idea is that Darren runs E4 behind the scenes, and will be turning off the channel to make sure everyone places their vote. It's not like E4 will actually close down that day, but still, it's brave of the broadcaster to abandon its usual slate of shows, ads and promos. We're interested to see how the public reacts -- it's a little patronising to suggest all of Britain's youth is incapable of voting and watching The Big Bang Theory in a single day.
