What are some channels that offer live TV streaming online?

The Eternal Word Television Network and C-SPAN are two television entities that provide live streaming for some of their programs. ETWN is a Catholic network with programs on mostly religious themes, and C-SPAN streams live political events such as sessions of the U.S. Senate or House.

EWTN provides constant live streaming for almost all of its programs. C-SPAN provides limited live streaming. The service requires users to have an account with an associated television provider to take full advantage of its live programming. C-SPAN archives many of its programs on its website; the programs are then available to watch for free.
