After the December 16th, 1997 airing of Pocket Monsters Episode 038, "Cyber Soldier Porygon," OLM went back over the first 37 episodes of the TV series and re-edited them to reduce any strobe lights, flashing, quick background color changes, or any other special effects that even slightly resembled the types of images that sent all those children to the hospital during the "Pokémon Shock" incident. This was probably done both out of an abundance of caution as well as an attempt to show the public at large that OLM and every other party involved was taking the incident seriously.

Thankfully, the versions of Episodes 2 - 37 that the Japanese Hulu site has of the series are all the pre-Porygon edits, meaning it is now possible to do side-by-side comparisons of the changes made.  Below is a gallery of those changes. The 1997 original broadcast version is on the left while the 1998 re-edit is on the right.
