Traditions, eventual rules changes are mentioned aspects that have more impact than TV improvements on the audience. Still, NHL TV shots and TV marketing have a lot of room for improvement as they are so poor at the moment despite being very important for a sport that need commitment to be properly exploited on TV. So the argument is of course worth discussing.
Let's face it, even us hockey freaks we often lose the puck. How can we pretend that an unexperienced disinterested viewer can be caught by something he can't follow??
Several things suggested along this thread are interesting and would help, but i can't believe that what is always my biggest concern (as the quote in my profile shows) is not even mentioned here!
At too many NHL facilities shots are too low and away from the boards. When you see a game with those LOW far shots you almost lose one viewing dimension. Rinks are on two dimensions, lenght and width. As simple and stupid as this remark can look, it seems this is sadly forgotten by those who employ those shots that make the rink lose its width for viewers eyes!
For god's sake, bring SHOTS UP and over the rink as much as you can!
Higher shots let you 'appreciate' the other dimension (width) too.
This instantly brings some key results:
-a BETTER vision/reading of the play development.
-let you better realize where there actually is some room on the ice, while with low shots it seems all closed even more than what really is.(cause you fully perceive only the lenght of the rink).
-make it easier to see the puck! The more enlarged the ice surface on your screen is (i am talking of the ice largeness on the screen, not the real one that it's evidently always the same. The concept is that with lower shots 2 square metres of real ice surface are shown on, say, 3 square cms on the screen, instead of the 4 or 5 square cms you could have with higher shots. That increases proportionally with the perceived width), the less hidden the puck will be. Not only, given its shape on the ice (it's way wider than taller) the puck is more visible from over than from aside.
Another important thing has been mentioned before by HckyFght (btw, i completely agree on his critic against NHL typical shortsightedness that has been holding the league back forever.., they hurt the game to not give up on 25 seats or on 20 days of regular season every four years for the Olympics..):
Put one camera for each zone. One for the neutral and one for each offensive zone. The latters will be useful to better follow/watch most of the situations in the zones, especially those in the angles.
The third important thing is better image resolution, of course, and that has been already underlined along this thread.
So, reassuming, there are three achievable things that would improve a lot the quality of the product on TV (even with the same product on the ice):
1-HIGHER SHOTS
2-at least 3 lateral cameras (one for each zone)
3-better resolution
As for the generic 'INCREASE the number of cameras and shots available', that would be a good thing only if used properly. I mean, the more chances you have to shot the play, the more chances you have to miss the right shot, especially if you are not an hockey expert. To have particular, alternative shots would be interesting of course, but useful only if used with moderation, most of them only during replays.
Then there are a couple of things about TV marketing too.
-The first rule to follow for a non-traditional sport (as it is in US) to get any kind of popularity is visibility. How can you think to get more fans' interest when the games in certain areas are broadcasted only on pay Tvs??! That's the best way to hidden a sport and to inevitably make it even more a niche-sport.
-NHL worries are all for the US market, and that's perfectly understandable, but why not to exploit all what (whatever it is, probably more than many think) the European market could offer?
In Europe it's difficult to be able to watch any NHL games, let alone the teams you would really like to see. There are countries like Switzerland, with many hockey fans, where there are not any TV offers (center ice,..) that let the ones willing to watch to pay for the NHL games they wanted. NHL should not only worry about getting new fans, but also to at least being visible for the ones already willing to watch.
