Google vows to change advertising policy following backlash from major brands

Google said in a blog post it would give advertisers more control over where their ads appear on both YouTube, the video-sharing service it owns, and the Google Display Network, which posts advertising to third-party websites and against search engine results.
The announcement came after the UK government and the Guardian newspaper stepped up pressure on YouTube to police content on its platform, pulling ads from the video site because they appeared beside clips they view as inappropriate.
