The Twins are a bigger market, for sure. Minnesota and Wisconsin are similar in size but where the Twins get to spread out across Iowa and the Dakotas, the Brewers are squeezed by the Twins from the west and the Cubs/Cardinals from the south.
Twins Daily is currently in its... 12th season? I think? So yeah, it's been around for a lot longer.
If Brewer Fanatic ever gets to 75% of Twins Daily's current size, I'd be thrilled. But had you asked me six years ago, I would have been ecstatic if Twins Daily was half its current size so... *shrugs*
Twins Daily is a bit of a unicorn. Its size and scope punches so far above the weight class of a mid-market upper midwestern team. During the height of the Carlos Correa saga in Dec/Jan, one tracking website had Twins Daily as the 19th busiest baseball website on the internet (it more regularly sits in the 40-ish range). The 19th most popular baseball website on the entire internet. My mind still reels at that thought.
