Issuu is an online service that allows for realistic and customizable viewing of digitally uploaded material, such as portfolios, books, magazine issues, newspapers, and other print media. It integrates with social networking sites to promote uploaded material. Issuu's service is comparable to what Flickr does for photo-sharing, and what YouTube does for video-sharing. While most of the documents are meant to be viewed online, some can be downloaded and saved as well. Uploaded print material is viewed through a web browser and is made to look like a printed publication with an animated page flip options.
