IMDb's history began on a 'message board' in 1990
The Internet Movie Database began as postings to Usenet, which essentially was a message-bulletin board. It began as posts on: "rec.arts.movies.movie.database" Usenet Newsgroup. This is mentioned here:
And, just like each message board which today resides at the bottom of each movie and TV series, people were in those days able to comment, ask questions, discus, that particular movie, TV series etc.
So it is ironic that IMDb is going to shut down a part of its history. If it wasn't for the "rec.arts.movies movie database" Usenet (which resembles a bulletin and message board) the creator of IMDb would have had to wait until the "Internet" was invented in order to begin the website. And without Usenet, there would have been less inspiration to create a site in the first place.
I certainly hope this fact is taken into consideration and that the boards don't shut down.
