It's been around for a while, CSPAN is the cable option that permits everyone to watch certain public affairs proceedings on TV (generally not live, but usually within a day or two.) You can watch a number of proceedings live online too, the website is chalk full of resources.
Schools are certainly using the resources and options available through the CSPAN option.
But I'm curious how many people other than the odd house mom (this is a satirical over generalization) gunning for a particular lobby group, actually watch CSPAN on tv at home?
100 million have the option on their tvs, but I bet a fraction of that # even knows the channel exists. Too bad, because there's nothing like a rousing committee meeting to bide the afternoon siesta. .....
