I don't often get surprised on the internet, but I was with this one. Star Trek as a TV show and it's descendents didn't get into the CGI world until part way through DS9. Babylon 5 was the first TV show to do all digital space shots from the start, in 1993. It turns out that the guys on TNG did experiment with CGI, but when they started, back in 1987, the technology just wasn't there yet.
Apparantly this was an extra on a DVD/BluRay set that only came out in the States and Germany.
