Twitter has said it had become profitable, disclosing that its live messaging service is carrying 130 million daily tweets, or short messages, from its members.
The US-based company, which has been one of the fastest-growing social-networking services, said 40 per cent of tweets are transmitted by mobile devices, typically smartphones.
“We’re making money,” chief executive Dick Costolo said in Barcelona at the Mobile World Congress expo, but gave no figures.
Twitter sets a size limit of just 140 characters on each communication. Each tweet goes to a user’s mixed collection of followers.
Founded in 2006, Twitter has been slow to develop a sustainable business model, with its originators opposed from the start to heavy advertising for fear this would put users off.
Costolo has ushered in a more advertising-centred approach, partly focussed on charging companies to tweet. He said further products to earn revenue would be coming up this year.
