Liberated Syndication (shortened to Libsyn) was founded as WebMayhem, which was incorporated in Pittsburgh by students at the University of Pittsburgh David J. Chekan, Matthew T. Hoopes, Martin Mulligan, and David Mansueto.^{[citation needed]} They established the company as Emayhem in 1998, as an art collective / publishing platform created for Pittsburgh artists and musicians to share their work online. They morphed that business into a web design firm called Webmayhem in 2000 and in 2004, they started the Emayhem Radio Podcast and created their first RSS feed. In an effort to save money, Mansueto leased some cheaper servers and laced them together, effectively creating a content delivery network (CDN). This CDN would become the first podcast hosting platform, allowing independent creators to upload media and syndicate it.^{[citation needed]}
