It's not actually the "glow puck" that appeared on Fox years back.  Then the puck was actually highlighted during play, whereas the Versus incarnation is reported to be used mostly for replays to highlight the route the puck took to the net.

One thing I will say about Fox is at least they were trying to grow the game back in the mid-90's.  And, largely thanks to exciting teams like the Avs and the Av-RW rivalry, plus some pretty good marketing (hello, buttman, is thing on?) they were somewhat successful.  Some folks even thought the NHL might catch and surpass the NBA at the time.

Having said that, being someone who knows the game well enough to follow the puck, even on TV, without it, I didn't like it.  The two really weird things about it were:

1. When the puck was along the near boards, the blue glow showed up in the stands, which was just strange.

2. On a slapper, the glow turned red and left a tail like a comet.
