SlideShare is a Web 2.0 based slide hosting service. Users can upload files privately or publicly in the
following file formats: PowerPoint, PDF, Keynote orOpenOffice presentations. Slide decks can then be
viewed on the site itself, on hand held devices or embedded on other sites.[2] Launched on October 4,
2006, the website is considered to be similar to YouTube, but for slideshows.[3] The website was
originally meant to be used for businesses to share slides among employees more easily, but it has since

2. expanded to also become a host of a large number of slides which are uploaded merely to
entertain.[4] Although the website is primarily a slide hosting service, it also supports documents, PDFs,
videos and webinars.[5] SlideShare also provides users the ability to rate, comment on, and share the
uploaded content. The current list of SlideShare's investors includes Venrock, David Siminoff and Dev
Khare.[6]
The website gets an estimated 58 million unique visitors a month,[7] and has about 16 million registered
users.[citation needed] SlideShare was voted amongst by the World's Top 10 tools for education & e-learning

Zipcasts
[9]
In February 2011 SlideShare added a feature called Zipcasts. A Zipcast is a social web
conferencing system which allows presenters to broadcast an audio/video feed while driving the
presentation through the Internet. Zipcasts also allows users to communicate during the
presentation via an inbuilt chat function.
Zipcasts do not currently support screen sharing with the presenter, a feature available in
competing paid services like WebEx and GoToMeeting. Additionally, presenters using Zipcasts are
not able to control the flow of a presentation allowing viewers to navigate back and forth through the
slides themselves.
