Telegram surpassed 500 million active users. In the past 72 hours alone, more than 25 million new users from around the world joined Telegram.

Instant messaging app Telegram is “approaching” 500 million users and plans to generate revenue starting next year to keep the business afloat, its founder Pavel Durov said on Wednesday. From a report:Durov said he has personally bankrolled the seven-year-old business so far, but as the startup scales he is looking for ways to monetize the instant messaging service. “A project of our size needs at least a few hundred million dollars per year to keep going,” he said. The service, which topped 400 million active users in April this year, will introduce its own ad platform for public one-to-many channels — “one that is user-friendly, respects privacy and allows us to cover the costs of server and traffic,” he wrote on his Telegram channel.
