I sort of recollect the White Sox being more of a national attraction up until at least 97 and maybe 98 or so and Wrigley/Sammy becoming the stars of Chicago and the country after that. The Cubs weren't really national until then. No big stars, not competitive, etc. You had Harry Caray and WGN and that was about it. The Sox had Frank Thomas, MJ on the Barons, rappers wearing the caps, and generally being more competitive.
