Shot Clock on the Floor: The New Yellow Line

See that red box down near the baseline that has the number 30 transforming into the number 29?  That's the shot clock.  And in this Duke/Florida State game today, it was the first time I have ever viewed this innovation.  Is this new?  I feel like I watch a lot of college basketball, but maybe the B1G network games are slow on the technology uptake?

I really liked this box and it increased my interest in the game.  This seems like another innovation that brings us one step closer to the idea that stadiums and arenas are increasingly becoming "glorified studios" for the tv audience.  As the cash from tv becomes so big, the fans attending the game become less and less important.  Guess who didn't see the shot clock box?  That's right:  those folks who are in the stadium.
