I think I remember watching it either during the 1997 or 1998 playoffs and thought it was cool, the robots however I thought were goofy. I saw more of it on Sportscenter than anything else and Dan Patrick would always joke about it. The last year of the NHL on Fox they took it away and that was disappointing, 9-10 year old me wasn't yet into Hockey and that was the best way to get a big NBA nut like myself at that time to watch Hockey on TV.
I know it got ridiculed back then and even today, but I'm sure for a lot of kids like myself who were watching Michael Jordan, Deion Sanders, and Ken Griffey Jr but had no Hockey heroes since the sport wasn't accessible and/or easy to follow on TV, the glow puck was the coolest thing about the NHL, and it's one of those things that just screams 1990's.
I'm not sure I want it to return however. The nostagila of it and other items of Hockey and other sports past back then doesn't always translate well to todays market. Sure kids would probably love it but I don't think it would win over many new fans, the point is Hockey in general is a tough sport to watch on TV. Anyone who wants to get into the game needs to go see it in person to truly appreciate it IMO.
