The "Fairness Doctrine" never forced anything directly. It just threatened the licenses of station owners if they were not "fair." Liberal shills filed complaints with the stations which had to be passed on to the FCC.
So the owners had a choice: give away air time to everyone wanting to express opposing opinions to the hosts' opinions or switch format to -- shudder - Top 40.
RE: "make us listen to an alternative"
Check out the reveiws of Cass Sunstein's book, "Republic.com," winner of 2002 New York Book Show Award.
Sunstein is a good buddy of Obama's and is up for an important czar in the Administration.
Sunstein's book does advocate government force to make us read alternate opinions on the Internet -- and he is no fan of FreeRepublic.
His latest book Nudge: Improving Decisions about . . . argues that alternatives should be structured so that government approved choices are the only ones from which citizens have to choose among, "libertarian paternalism."
Because the plan is to drive broadcasters who carry conservative talk radio out of business.
