Mahmoud Ahmadinejad's brief visit to New York City sparked a fiery amount of attention in Buzz. Searches for "ahmadinjead" blew upwards nearly 1,000% over the past week and "iran president" surged 2,317%. The Iranian's blistering remarks at the United Nations boosted queries for "ahmadinejad un speech," but most of the online notice focused on his gig at Columbia University.

Student protesters swarmed the college campus and packed the auditorium to hear Columbia President Lee Bollinger introduce (and slam) the Persian leader. Online, demand for "ahmadinejad columbia transcript," "ahmadinejad columbia speech," and "ahmadinejad at columbia" erupted.

The private school's invitation to the firebrand politician brought it both scorn and praise. Buzz for "columbia university" soared. Many searchers hit the Web for more on "columbia iran" and "columbia university ahmadinejad." That's one association the school's trustees surely don't relish.
