Twitter has filed for an IPO. The news was revealed, unsurprisingly, in a Tweet from the company’s official account. Analysts estimate the company’s value at around $10bn (£6.3bn).
eMarketer predicts that Twitter will earn around $583m in ad revenues this year, rising to just short of $1bn in 2014. Around $308m of this $583m will come from mobile ads.
The move was most likely forced on Twitter because it had passed the number of private investors – 2,000 – that require a US company to file for an IPO, though Twitter has not confirmed this. 
Speaking at the Mobile Gaming & Gambling Summit ealriet this weeks, Twitter’s head of agency sales in the UK, Dara Nasr, revealed that the company had 15m users in the UK, 80 per cent of whom access the social network via mobile. He also revealed that it took Twitter three years to amass its first billion tweets, a figure it now achieves every two days.
