Just the other day I was wondering when was LBT mentioned on the Internet for the first time. So I started searching through old newsgroups, and I found
this.
The Land Before Time appears on a list of romantic movies on March 20th 1989. Quite old, isn't it?
Also in
1989 there are a number of other discussions where it was mentioned, and for the first time there are Internet users to whom LBT is the best movie of all time, the first online fans.
And in 1990 there was a
rumor circulating that Bluth was working on Land Before Time 2, in fact, the movie was supposed to be in post-production (it is listed with a bunch of movie titles that did eventually appear), but now we know that it wasn't true, alas.
In 1991 and 1992 discussions get more varied, including a request for GIFs from LBT, and discussions on the supposed Horner's plagiarism of works of other composers.
If you want to search a particular year, use this search format
"land before time" before:YYYY/MM/DD after:YYYY/MM/DD
By 1995 LBT appeared in a number of various discussions, but there was no dedicated LBT discussion group.
I thought you would be interested in this blast from the early Internet past.
