Clarification on Part of Supplement Question?

I’ll be applying RD for Columbia this year, and one of the supplements states:

“List the titles of the print, electronic publications and websites you read regularly. (150 words or less)”

What is this limited to? I’m assuming newspapers and magazines count, such as The New York Times, The Economist, etc, but what about websites? Does “electronic publications” refer solely to journals published on the internet or does this include websites as well? For example, would Khan, TED, or another such website count or would they miss this question’s premise?

They are curious about what informs your thinking.
