SlideShare

SlideShare is a Web 2.0–based slide hosting service. Users can upload files privately or publicly in the following file formats: PowerPoint, PDF, or OpenDocument presentations. Slide decks can then be viewed on the site itself, on hand held devices or embedded on other sites.

Founded in 2006 with the goal of making knowledge sharing easy, Slideshare joined the LinkedIn family in 2012 and has since grown into a top destination for professional content. With over 18 million uploads in 40 content categories, it is today one of the top 100 most-visited websites in the world.
