It is less than a week until the NAB Show in Las Vegas. Meanwhile, MIPTV will be taking place in Cannes, in the south of France. 4K ultra-high-definition will be a theme at both events, promising to be the next big thing in television. In London a new television channel launches today. Although the city is not short of broadcasters, it’s the first channel dedicated to the capital, one of a number of local stations being rolled out across the country with low budgets and high hopes. We wish them well.
