In 2004, Skype's first year, only 1 million users used the platform at once. The most significant jumps occurred during the last two years. In 2011, 30 million people made Skype calls at the same time, which is less than half the number concurrently connected earlier this week. Statist pulled the data in this chart from Skype's real-time user figures and the Skype Numerology blog.
