Examples of Internet services:

Flickr (/ˈflɪkər/ ⓘ FLIK-ər) is an image and video hosting service, as well as an online community, founded in Canada and headquartered in the United States. It was created by Ludicorp in 2004 and was for a time a common way for amateur and professional photographers to host high-resolution photos.[4][5] Flickr was owned by Yahoo! from 2005 and has been owned by SmugMug since 2018.[6]

As of June 10, 2015, Flickr had a total of 112 million registered members and more than 3.5 million new images uploaded daily.[7][8] On August 5, 2011, the site reported that it was hosting more than 6 billion images.[9] In 2024, it was reported as having shared 10 billion photos and accepting 25 million per day.[10] Flickr also hosts the largest collection of Creative Commons-licensed photos on the web.[11]

Photos and videos can be accessed from Flickr without the need to register an account, but an account must be made to upload content to the site. Registering an account also allows users to create a profile page containing photos and videos that the user has uploaded and also grants the ability to add another Flickr user as a contact. For mobile users, Flickr has official mobile apps for iOS,[12] Android,[13] and an optimized mobile site.[14]
