Odeo

Odeo was a directory and search destination website for RSS-syndicated audio and video. It employed tools that enabled users to create, record, and share podcasts with a simple Adobe Flash-based interface.

Odeo was originally developed by founders Noah Glass and Evan Williams, who were previously founders of Audioblog and Pyra Labs, respectively, and received funding from Charles River Ventures. Subsequently, Williams bought out Charles River's interest in the company, as well as that of several other investors, and re‑formed the organization under a new company, Obvious Corp, which planned to develop new products, including Twitter.

On February 19, 2007, Williams wrote in his blog that Odeo was for sale. It was acquired soon afterwards by New York-based Sonic Mountain.

On September 14, 2007, Sonic Mountain announced that it had acquired the technology assets of FireAnt, an RSS video-aggregation website and desktop media player, and that it planned to incorporate FireAnt's technology into Odeo. On March 18, 2008, Sonic Mountain announced that it had acquired Blogdigger, a search engine for blogs and RSS content, with plans to incorporate the technology into Odeo. In June 2008, Odeo was relaunched by Sonic Mountain with a completely redesigned site and an expanded focus on search and discovery for syndicated audio and video.
