[CR]Campagnolo Pedals w/Loops Question

I've searched the archives along with Chuck's Campagnolo timeline and could not find the answer to the following:

1. What year did Campagnolo delete the toe strap loops from their chrome plated, steel caged NR pedals?

2. Why did they delete the loop?

Thanks in advance,
