The ability to block online ads could soon come from an unlikely source. Instead of installing a browser extension or a third-party iOS app, there's a chance Brits will be given the option by their mobile network. We've heard rumblings of this before, but now a UK carrier has confirmed it's looking at such a feature; EE's CEO Olaf Swantee tells The Sunday Telegraph he's launched an internal "strategic review" to see whether customers should be given "more choice and control over the level and intensity of ads on mobile."
