StumbleUpon was a browser extension, toolbar, and mobile app with a "Stumble!" button that, when pushed, opened a semi-random website or video that matched the user's interests, similar to a random web search engine. Users were able to filter results by type of content and were able to discuss such webpages via virtual communities and were able to rate such webpages via like buttons. StumbleUpon was shut down in June 2018. StumbleUpon was founded in November 2001 by Garrett Camp, Geoff Smith, Justin LaFrance and Eric Boyd during Camp's time in graduate school at the University of Calgary. A prototype was ready by February 2002 and, with great reviews, the extension was installed by thousands of users daily. However, at the time, the company did not advertise and generate much revenue.
