Comet TV does air in a steady schedule, and they cover over 72% of households in the US. They don't stagger for time zones but within a given time zone, ROH airs at the same time every late Wednesday/early Thursday depending on where you are.
And Comet does a nation wide live stream of the show on their website at the same time every week for free.
And just today they announced standalone Comet TV apps for Apple TV and Roku.
And that's just Comet. The non-Comet Sinclair affiliates cover over 30% of households alone, and those air at the same time every week too.
It's literally just NESN that is inconsistent.
Comet TV, local Sinclair stations, Fight Network, ROHwrestling.com, Fite TV, Comettv.com, etc all air ROH at the same time every week. Not all of them air at the same time as each other, because that's how syndication works.
Star Trek TNG didn't air at the same time in every market either, but people within a given market got it at the same time every week. Just like ROH.
