With 300 million accounts, Instagram has more subscribers than Twitter
The analyst said that Instagram is also growing its user base faster than Twitter is. On a year-over-year basis, the number of Instagram subscribers rose 22% in the third quarter. That figure comes from the bean counters at Barclays, and will slow down next year to a growth rate of 14.8%, according to eMarketer. Instagram itself says that 70% of its traffic comes from beyond the borders of the U.S. That would mean that 90 million Instagram users live in the states, as opposed to the 63 million Twitter users who live there.
Facebook paid $1 billion to buy Instagram in April 2012, (although a drop in Facebook's stock price took the final purchase price under the $1 billion mark) and has started to monetize the app using ads.
