Jim,
a recent campus Internet traffic analysis at Carleton is similar to yours and reflects national Internet usage trends: a third of traffic is Netflix CDN. On our campus YouTube is also a significant source of traffic.
Also of note. For campuses that are Internet2 connected, there was an announcement on June 6 that Netflix will be peering with Internet2 (see https://blogs.internet2.edu).

No question here. Just a data point. Inspired by the panel on content
distribution networks at the NANOG meeting earlier this week, I decided to
look at the amount of our traffic that comes from Netflix. Answer:

The graphs are for the whole campus, but at midnight when Netflix peaks,
there is no significant use outside the residences. Netflix is responsible
for 30 percent of the peak traffic on RESNet. While I put the source IP
addresses of our Netflix traffic on plot, unless your network is part of
CENIC, your addresses would be different.
