They used to teach these concepts back in high school.
(1980's, that is.)
By the way,
Are Rush and Hannity on XM and/or Sirrius Satellite Radio??
My wife has been hinting at getting one or the other for Christmas, but I don't want her to pull the trigger if Rush and Hannity aren't available.
Thanks. :)
I really don't know. Have you checked out their web sites? That might tell you.
I don't know about Hannity, but Rush has said that he won't ever be. He's on stations in every state, and he said that many of them are stations that took a chance on him years ago, when his success wasn't guaranteed.
He's not going to undercut their revenues by going on alternate broadcasts.
