LinkedIn has acquired SlideShare,  a site used to host presentations across the Web, for $118.75 million.

“Presentations are one of the main ways in which professionals capture and share their experiences and knowledge, which in turn helps shape their professional identity,” said LinkedIn CEO Jeff Weiner.

“These presentations also enable professionals to discover new connections and gain the insights they need to become more productive and successful in their careers, aligning perfectly with LinkedIn’s mission and helping us deliver even more value for our members.” 

SlideShare is a service for sharing PowerPoint, OpenOffice, or Keynote presentations. It allows material posted to Facebook or SlideShare or LinkedIn to be available to all three sites from any one.

Rashmi Sinha, CEO of SlideShare commented, “We built SlideShare to help professionals share presentations and connect people through content. What we can build with LinkedIn, the largest professional network on the Internet, is the most natural extension of this vision. I am excited about what we can build together.”
