The video was for "Everybody Wang Chung Tonight", which consisted of 
two scenes being flipped back and forth at around 10Hz throughout. It 
was a classic 80's video, but got lots of publicity in '87 for the 
epilepsy angle. Unfortunately, there's very little available in hard 
copy online, primarily because it happened before the Web, but the fact 
that there are researchers named Wang and Chung who have co-authored 
papers dealing with epilepsy doesn't help.

A similar, better documented example happened in December of 1997 in 
Japan with an episode of Pokemon. A survey of 4000 children showed .75% 
experienced seizures (and 10.4% experienced other effects such as 
headaches) while watching a certain scene:
