This cartoon is no doubt based on a real incident in which a children's cartoon broadcast
s of inverting primary colors
that were flashing around 15-16 times per second (every two NTSC frames
). This frequency
is likely to (and did!) trigger epileptic seizure
s in those susceptible. Apparently, some dozens of children did in fact have mild to severe reactions to the broadcast.
My swiss cheese memory has lost the title of the cartoon; however, I know that this happened in the last couple of years, and that it was eventually broadcast in the U.S. with the backgrounds toned down and the frequency changed.
UPDATE: Break has helpfully informed me that was no less than Pokemon the cartoon which was the culprit. :) From his info, the incident occurred on Dec. 16th, 1997, and resulted in 658 people being hospitalized (more than the 'few dozen' I had thought!) with several hundred required extended hospital stays. Ouch!
