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. The company was founded in 2006, with the service launched December 2007. Issuu was selected as one of TIME's 50 Best Websites 2009 and was a 2009 Webby Awards Honoree and a 2008 South By Southwest finalist. Notable Issuu clients include Routledge, The World Bank and Cambridge University Press. In December 2008 Issuu released Smart Look, which allows other websites to convert their hosted documents to digital Issuu editions, so readers do not have to download the documents to read them.
