It was founded by Stewart Butterfield and Caterina Fake in 2002.<ref>https://www.inc.com/magazine/20061201/hidi-butterfield-fake.html</ref>It is also an [[online community]] platform, which is considered an early example of a [[Web 2.0]] application. Users can upload any photo to their website. The user will then be asked to release the photo under many licenses available. Some licenses allow other people to reuse it, which makes it possible for [[Wikimedia Commons]] to transfer free files from Flickr to their website. Any person that has a Yahoo! ID can register their Flickr account in a few seconds. == Service == Flickr provides a free service for users to share their photos online with other people. However, free users have a limit of 300 [[Megabyte|MB]] of uploads per month, 15 MB per photo and 150 MB per video.<ref>[https://www.flickr.com/help/limits/#65 Flickr: Help: Free Accounts, Upgrading and Gifts] - Retrieved December 19, 2010</ref> However, users can upgrade to the pro account where they can get unlimited uploads at $24.95 per month.<ref>[https://www.flickr.com/upgrade/ Flickr: Upgrade to a pro
