Google has vowed to take a tough line on copyright when it completes its $1.65bn (£875m) takeover of YouTube.
The video-sharing website’s rapid growth has been partly down to the thousands of clips from old TV shows uploaded illegally by its users.
But Google Europe vice-president Nikesh Arora told MPs his company would not tolerate copyright violations.
YouTube is thought to have escaped prosecution so far because it is a new business with little cash, MPs heard.
Its policy is to take down copyrighted material when it is alerted by the owners, but it has been criticised for not being vigilant enough.
