YouTube to adjust UK algorithm to cut false and extremist content

Views via recommendations of such 'borderline' videos were halved in similar US trial

YouTube is experimenting with an algorithm change to reduce the spread of what it calls "borderline content" in the UK, after a similar trial in the US resulted in a substantial drop in views.

According to the video sharing site's chief executive, Susan Wojcicki, the move is intended to give quality content "more of a chance to shine" and has the effect of reducing views from recommendations by 50%.
