"From NBC in 2020-21 to TNT and ESPN in 2021-22, this season marked the biggest increase in overall average viewers ever.
The NHL's new media (and broadcast) rights deal has attracted more new viewers watching hockey than ever before. With the Stanley Cup playoffs consisting of nearly 25% of new NHL viewers. That's big.
Overall, the 2021-22 season averaged 52% more viewers per game than last season.
The hype around the NHL was real this season, and the new TV deal was the main factor." - PuckEmpire
