Los Angeles-based Hulu, the online video streaming site, is apparently in efforts to file for an IPO, as a long line of Southern California firms heads towards the public markets. According to a report in the New York Times, Hulu is in discussions with investment bankers about pursuing an IPO in the fall. No details of the potential IPO have been released. Hulu would be just one of more than a handful of local firms headed towards an IPO. The latest firms with Southern California connections to file for an IPO are REVA Medical, Gevo, and Demand Media; recently IPOs have been Green Dot, RealD, Trius Therapeutics, and ReachLocal.
