Indeed it is. See http://en.wikipedia.org/wiki/Peering and 
http://en.wikipedia.org/wiki/Tier_1_network for more information. I'm 
guessing you are using Tier 1 to refer to $LARGE_TELCOS (ATT/VZ/L3)
and I'm guessing their sustained daily traffic volume is well over 10tb.

Facebook and google probably push that much traffic daily. I used to 
work for a company that did 100Gbps sustained on a daily  basis.

I agree.
