The United States Supreme Court on Wednesday reversed an earlier ruling and says that Aereo does indeed violate copyright law. The company has been in a bitter battle with broadcast television networks that have argued Aereo is simply stealing content and selling it to customers through subscription packages.

As CNBC notes, Aereo has long argued that it's not actually charging for the content but for the technology that allows it to provide mobile applications and TV channels on mobile devices. The CEO of CBS Leslie Moonves has even threatened to take his content online-only if Aereo prevailed at the Supreme Court level.

The company has deployed antennas all around the markets it offers its service in, such as New York City, Cincinnati, Dallas, Detroit, Houston, Boston, San Antonio, Miami and others. Aereo provides access to CBC, NBC, FOX, ABC, CW and PBS as well as syndicated channels, home shopping networks and more. Its service can be accessed on iOS and Android devices, as well as connected products like the Apple TV, Roku and Chromecast, and through desktop browsers.

The ruling suggests Aereo may need to change the way it operates very soon.  TechnoBuffalo reached out to Aereo for comment, but a spokesperson was not immediately available. We'll let you know as soon as we hear more.
