Heh. Brings to mind the Fox Sports 'FoxTrax' [1] which placed a glow on the puck. Hockey fans hated it. I'm not sure if non-hockey fans cared either way.
Oh no, the glowing dot! But remember this was well before HDTV. Watching hockey on a grainy old TV was not accessible for those who didn’t know the game. However, I don’t think it was successful in bringing in new viewers, and people who were already fans hated it because, well, it sucked.
With the puck tracki technology being reused for advanced stats fans, I wonder if they'll try something similar except make it optional on web broadcasts or will the FoxTrax legacy prevent them from attempting it.
