YouTube tries to fight off rivals for top video stars

Google's YouTube is in "fire drill" mode, according to a person close to the video service, The Wall Street Journal reported. YouTube is offering bonuses to some of the top video-makers to sign multiyear deals in which they agree to post content exclusively on YouTube for a time before putting it on a rival service.

Competitors Facebook and Vessel are trying to lure away the talent, the Journal said.
