Revenues rise past $2bn after 45pc jump in people viewing Facebook via mobile phones but shares fall as it admits younger teens use site less
"Our best analysis on youth engagement in the US reveals that usage of Facebook among US teens overall was stable from Q2 to Q3, but we did see a decrease in daily users, specifically among younger teens."
Around 874m people a month now use Facebook via mobile phones, up 45% in a year.
Revenue from advertising was $1.8bn, a 66% increase from the same quarter last year. Mobile advertising revenue accounted for approximately 49% of advertising revenue for the quarter.
Facebook has, however, delayed the roll-out of video advertising, and of advertising on its Instagram photosharing platform, which Mr Zuckerberg bought for $1bn.
Investors expect video to play an increasingly important part in the future advertising revenue of the site, but have largely welcomed the cautious approach to any roll-out.
The results meant the site’s share of the global advertising market has surged to an unprecedented high and it now accounts for more than 5% of this market online and around 25% on mobile devices.
