Call Sign Meaning
I've been adding WISconsiN as a call sign meaning for quite some time now only to have it deleted by another user who INSISTS that the only possible meaning for the calls is the defunct WISconsin News newspaper.  As far as I know, there is no official documentation or credible source that states that the calls are a reference to the newpaper and the newspaper ALONE.  So who's to say the calls weren't also chosen because it was an abbreviation of the state's name?  There's plenty of examples of a station using calls with multiple meanings (such as WBBM-TV out of Chicago).  But my main sticking point is that WISN has referenced the calls while advertising itself as "WISconsiN TV" (http://www.youtube.com/watch?v=7JFirQUXfc8)  My theory is that the station chose to keep the calls after the newspaper folded because they referenced the state's name as well (the station had only been using the calls for a few years when the paper folded, so the "name recognition" argument is moot).  But regardless of why they kept the calls, I think the fact that the station made a conscious decision to use them to brand itself as "Wisconsin TV" deserves mention.
