11 February 2014 Last updated at 11:47 GMT

In the latest #BBCtrending radio, the team have been looking at how Flappy Bird - a highly addictive computer game recently launched by a programmer in Vietnam - came to trend globally across social media.

Also on the programme, Russians hit back at the hashtag #Sochiproblems, why a cleric in Saudi Arabia accused football fans of taking their support too far, and how social media forced an "unprecedented" apology from Iran's President Hassan Rouhani.

Mukul Devichand is joined in the studio by Lina Rozovskaya, Camelia Sadeghzadeh, Sumaya Bakhsh and Mike Wendling.
