Testing issues are holding Aereo back from releasing its streaming broadcast TV service in Chicago this month, the company announced today. The Chicago release was originally slated for September 17th, but the company says that "issues with our beta site" have caused it to delay the launch.

Aereo relies on an array of tiny, dime-sized antennas (pictured above) to capture broadcast TV signals, streaming the shows to customers over the internet. Previously limited to New York (but quickly expanding), the service has raised the ire of networks like CBS and Fox who claim that by redistributing free broadcast programming, Aereo is effectively stealing and re-selling rightsholders’ content. So far, Aereo has successfully managed to fend off those charges in court.
