Flickr is a photo and video sharing website. Flickr was developed by Ludicorp in Canada. They launched Flickr in February 2004. It was originally a game called The Game Neverending,a massive multiplayer game for all the world. Users load their photos on the site and make them available to all other users (if privacy settings allow this).Similarly to Facebook, photos can be 'tagged', meaning that they are specifically labelled with a word, or a specific preson. So when another person searches the word, the photo tagged with that word will come up.In this way, hundreds of photos can be grouped into a category about that place or person. Photos can have lots and lots of tags so different people can easily share them. Now a new form of tagging has appeared, 'geotag'. This is, if a camera has GPS, then the photo will appear on a map.By this tagging, people can comment on each photo and each photo has a history of people who were there, or who remember something else about it. After 5 years in operation, Flickr claims to display more than 3 billion images. Each one of them has masses of information so the website holds so much information.
