Half time scores over the PA

I think I'm correct in saying scores from around the division & country are not given out over the PA at half time nor full time?
For those who prefer to stay in their seats at half time rather than spend 10 minutes being jostled on the concourses wouldn't this be something that can be addressed in future either on the big screens or over the PA......(i'd get the scores on my phone if i could get a decent signal but that's another story).

If this cannot be done, what's the reason?

Difficult one, as we actually get more complaints when we read the scores than when we don't - as a large number of fans do not want to know scores (particularly from the Premier League) so they can watch highlights, without knowing the outcome of games. Currently, we just read and display the Championship scores.
