YouTube Introduces Video Advertisements

Video advertising has started on the YouTube website, according to its internet giant owner, Google. Google said it had designed the way the advertisements work on the video-sharing website to be as unobtrusive and undisruptive as possible. The advertisements will begin 15 seconds after a user has started to watch a video, but only on 20% of the screen window. Google said the advertisement would then disappear within 10 seconds if the user had not clicked to watch it.
