ESPN3 is not a channel that can be accessed through AT&T’s U-verse or any other cable service provider to watch regular television. Instead, ESPN3 is a streaming service offered online by ESPN that includes part of the ESPN networks’ content. WatchESPN.com is where you can find ESPN3.
ESPN3 aims to provide access to content that goes far beyond what the ESPN network is able to broadcast on its primary channels. For instance, ESPN is physically unable to broadcast more than one game per channel for each time slot throughout the day on a Saturday in the fall.
In addition to the nationally aired alternatives on ESPN, ESPN2 and ESPNU, ESPN3 enables the corporation to provide access to additional games that can have regional or specialised appeal through its website.
