I completely understand why the club might want to put a big screen into the ground, primarily, I'd assume, as a way to make money from advertising but also perhaps to showcase some of the Argyle TV offer. It makes sense from that perspective and I'm supportive of the club trying to find ways to generate revenue to build the club infrastructure and playing squad.
What I don't understand is why so many fans are keen on the idea of having a big screen in the ground. I can't really see what the attraction is. Most people seem to be generally anti having advertising thrust in their faces (e.g. look at the constant grumbling about adverts on PASOTI) and I really can't see how having anything on the screen during play, other than the scoreline and time, could be anything other than distracting. That just leaves the time before games, at half time and after the game when showing Argyle TV footage might work but then do people REALLY want to go to Argyle and watch a big TV in a corner of the ground. You can always watch TV/screens at home or on your phone. Surely people want to take in the match atmosphere, talk to mates about the game etc.
Personally, I understand why having a big screen could be an attractive proposition for the club but I don't understand why it's attractive to fans. I don't feel any personal need to have a screen in the ground and think it's nice to get away from screens and immerse myself in the real match experience when I go to games. So I get why the club is doing this but I'm not in favour of it myself.
