Many companies such as Comcast, Cartoon Network and ABC provide various services for streaming live TV. The streaming services offered by these three companies are diverse in function and accessibility, some depending on location and subscriber status while others are freely accessible to anyone with access to the Internet and a connection of decent speed and bandwidth.
ABC Go is an online regional streaming service accessible depending on user location. If the user's IP address corresponds to a serviced location, then they can quickly and easily access a live stream of their regional ABC affiliate any time, as long as they have Internet access.
Comcast XFINITY is a service available only to Comcast subscribers who have set up their online accounts. These subscribers can watch and stream many programs from live streaming sites affiliated through the Comcast hub site. This gives them access to a huge range of programming from within the provider's network of television channels and services.
Cartoon Network provides a free streaming service to all Internet users. This gives them access to a live stream of the channel's programming. They also maintain databases of many already broadcast episodes of shows on their roster, allowing users to watch old episodes at their leisure.
