Photo sharing sites which are popular include Flickr (a Yahoo! service), Picasa (a Google service), Photobucket, Webshots Community, Kodak Gallery, Image Shack and SnapFish. These rely on tagging to enable users to find related shots they are interested in and can be used to create mashups using widgets to embed the object into a blog or other site. Some online campaigns for high-involvement products such as cars or holiday now invite customers to submit their own pictures via services such as Flickr to build ongoing interest in a campaign.
Video sharing sites include Youtube, Google Videos, Jumpcut, Grouper, Revver, Blip.TV, VideoEgg and Daily motion. These sites have very similar features to photo sharing sites but some add more features in the form of subscription to channels and offer code to embed the players on social networks and blogs.
Another form of sharing content is important in professional B2B markets in through slide sharing sites such as Scribd and SlideShare.net.
