ESPN3 is an online streaming service, so neither Cox Cable nor any other cable provider gives it a channel number. But Cox customers can stream sports events through ESPN3, including many ESPN and ESPN2 broadcasts.
People don’t need a cable subscription to watch non-televised shows on ESPN3, but they do need to log in through their cable provider to watch events on televised ESPN networks. Even though ESPN3 is a service that runs on the Internet, many streaming devices let people watch these shows on a regular TV.
Streaming of ESPN3 is possible on Roku, AppleTV, and Android-based standalone devices, among others. Users can also connect their laptops, tablets, or smartphones to their TVs if they have the right outputs.
