US internet giant Google is to begin running advertisements along with video clips on its popular sharing website YouTube.
A statement on the YouTube official blog said the ads would run as 'animated overlays that appear on the bottom 20% of a video'. The news comes 10 months after Google bought YouTube for $1.65 billion.
Although YouTube attracts nearly 190 million visitors per month, it has until now remained nearly free of advertising, and also revenue. Internet users can ignore the overlay ads, close them or click on them to go to the advertiser's page.
The ads, which automatically pause the video, will appear within the first 15 seconds of the launch of a video clip and end 10 seconds later.
Google said that it plans to post ads only on videos supplied by its official content suppliers, not on the amateur home videos which dominate the site.
