Jeff Agrest from the Sun-Times had an article about the ratings bump CHSN got from finally getting on Comcast, but it's from June:

The Chicago Tribune's Robert Channick had a more recent update on Oct. 6 with info on CHSN ratings (no info about how many subscribers they have), but it's behind the Trib paywall: https://www.chicagotribune.com/2025/10/06/chicago-sports-network-second-year/

From the article:

"CHSN is already seeing increased viewership with its full pay-TV distribution. From the All-Star Game on July 18 through the end of the season, White Sox ratings were down just 5% from the team's final season on its previous TV home, NBC Sports Chicago, the network said.

That still leaves plenty of upside, however. Last year, when the White Sox lost a record 121 games, the TV audience on NBC Sports Chicago averasged a paltry 0.7 rating, according to Nielsen data."
