I think you're referring to congestion over an ISP's network, if everyone were 
to watch live streams of the same program at the same time. There are measures 
that ISPs will no doubt be taking as time marches on. In this Superbowl 
example, the easiest solution over an ISP net would be to multicast (IP 
multicast) the show through the network. As long as the streams remain within 
an ISP's own network, this should be doable. And, of course, the bandwidth of 
these ISP nets is increasing steadily as well, and the number of servers 
deployed throughout.

This is the opposite side of the recorded content coin. What's easier to do for 
over a two-way, mostly unicast medium may be more difficult in the one-way 
broadcast medium, and vice versa. "More difficult" doesn't mean impossible, 
though. In spite of what the pundits and "our pundit" might have you believe.
