Teenagers are switching from Facebook to other social networking like WhatsApp, WeChat and KakaoTalk, according to the latest reports.

WhatsApp, which has a global active users’ base of 350 million, is said to be the most popular messaging app in the UK and is currently used by half the country’s iPhone users, according to a report from Mobile Marketing Magazine.

One more report from mobileYouth, cited by the Guardian, revealed that about half of the photos on Instagram comes from 14 to 21-year-olds.

Another 90% of the Brazilians, 75% of Russians and half of Britons are said to adopt messaging apps, while 95% of smartphones used in Spain are installed with WhatsApp, according to another report from Tyntec.

Some of the reports suggest young people are increasingly using the messaging apps because they provide a more private sharing space.

Facebook reported a 60% rise in revenues for the third quarter, driven by mobile advertising, accounting for about half of the revenues generated.
