Pennsylvania's version of Megan's Law first became effective in 1996.
The law required convicted sexual predators register on a database held by the state.
The database would be publicly available, insuring a community would know when a convicted sexual predator lived in their neighborhood.
This was 1996, when America OnLine, Prodigy and CompuServe were the Internet giants.
There was no Facebook, no Twitter, and if you told someone to Google something, they would look at you like you had three heads.
