StumbleUpon was a website, 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.^[1] Users were able to filter results by type of content and were able to discuss such webpages via virtual communities and to rate such webpages via like buttons. StumbleUpon was shut down in June 2018.
