I didn't see this mentioned anywhere else, so here's the news story. National revenue (I assume mostly from the TV deals) is up, but local revenue from ticket sales and the Titletown district was way down thanks to the government-imposed shutdowns.
Depending on the point of view of the reporter, either the Packers suffered their first operating loss in 20 years, or it's OK because they have a lot of money and the investment fund made up for it. Since they're the only team that has to release a report thanks to the Packers' unique ownership model, it offers one of the few looks into how teams around the league might be doing.
The Packers' own press release didn't have a link to the actual report, either.
