SlideShare began with a simple goal: To share knowledge online. Since then, SlideShare has grown to become the world’s largest community for sharing presentations and other professional content. SlideShare was founded in October 2006 and acquired by LinkedIn in May 2012. Individuals and organizations can upload and share PowerPoint, PDF, or OpenOffice presentations. Anyone can find presentations on their topic of interest. Users can tag presentation, and download or embed them into their own websites or blogs. Users can also share their documents privately.
