What's the earliest release you've got that features a web address or email on it?

A genuine question

I was listening to the compilation Cold Krush Cuts last night and noticed that the email address on it wasn’t a ninjatune.net address… but rather a .demon.co.uk one… and there was no Ninja Tune URL either. So this was reasonably early in the world of labels being online (1997).

I wondered, what’s the earliest release you can find in your collection? I’m pretty sure we can beat ‘97.

I’d appreciate any answers in the comments section.
