Social discovery tool StumbleUpon has reached a new milestone; its famous "Stumble" button has been clicked more than 25 billion times.
"Today we celebrate 25,000,000,000 clicks of the Stumble! button," StumbleUpon Community Manager Monica Semergiu said in a tweet.
The social media company has been on a roll ever since it was spun out from eBay in 2009. In November 2010 the social site hit 12 million users.
StumbleUpon reached 44 million stumbles in a single day last month and broke its mobile usage record during this year's Super Bowl. In April, the company hit 1 billion stumbles per month.
While StumbleUpon doesn't receive the same type of media attention that Facebook, Twitter, Foursquare or Google+ garner, it has quietly grown into a social media powerhouse with millions of loyal users. The result has been a solid business that will celebrate its 10th birthday in November.
