Oeo is an online application that allows for recording and sharing podcasts with a simple Macromedia Flash-based interface. It also contains a directory and radio, with podcast channels. Odeo was 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 several other investors, and reformed the organization under a new company, Obvious Corp, which planned to develop new products, including Twitter.
