SlideShare is an American hosting service, now owned by Scribd, for professional content including presentations, infographics, documents, and videos.

Rashmi Sinha, the CEO and co-founder of SlideShare was named among the world's Top 10 Women Influencers in Web 2.0 by Fast Company.

[9] On July 24, 2007, Slideshare introduced a format called "SlideCast" [10][11][12] to "make web multimedia using only a ppt file and an mp3".

On January 31, 2014, less than a year after its acquisition by LinkedIn Corporation, Slideshare announced that Slidecast would be shut down on April 30, 2014.
