NBL posts positive R1 viewership, attendance figures
From the NBL's article:
The seven games broadcast from Thursday to Sunday achieved more than 40% year-on-year increase in average audience on ESPN, via KAYO and Foxtel.
On top of setting a new viewership benchmark, the League also smashed its round one attendance record with almost 51,000 fans pouring through the gates.
"We welcomed an amazing 50,934 fans, eclipsing our previous best of 48,820 set in 2018/19," Stevenson added.
Solid start to the campaign, although from what I gather historical viewership numbers haven't been that high, so even after a 40% increase there may still be a lot of room for improvement. Still, trending in the right direction.
