Too Long; Didn't Read
Stewart Butterfield, co-founder of a gaming company, created a browser-based multiplayer online game with his team in 2002. Game Neverending reached its end of life in 2004, but the team kept one of the tools they used for internal communication of the game. The team evolved this tool into a new service: Flickr. Flickr. It launched as an image hosting service where you can upload, tag & group, and share your images. But it could not hold on for very long. Flickr acquired Flickr and also the team Ludicorp in 2005 for [$25m].
