No, absolutely not.
I wish they only did the promos at halftime. That is actually the time when they do the least number of them, presumably for the reason you gave.
The people I know that attend SU basketball games do not like the changes discussed in this thread. I know for at least 4 people that have dropped their season tickets with this as the primary causal agent.
IMHO, the fundamental disconnect is this: SU basketball is a great product. People go to the games to watch basketball and enjoy the college atmosphere. All the distractions, noise, piped in music, ads and other garbage constantly directed at the fans is not desired or helpful, and it hurts the bottom line in terms of money as well.
