YouTube sharpens how it recommends videos

San Francisco

GOOGLE'S YouTube has updated its recommendation feature to spotlight videos users are likely to find the most gratifying, brushing aside concerns that such an approach can trap people in bubbles of misinformation and like-minded opinions.

The new feature, which arrived in January but has not previously been reported, uses a measure of satisfaction derived from a massive and ongoing user survey to predict and promote videos that people would rank as among the best they have watched recently.
