I don't think many outside of government and education establishments used, or had email prior to 1994 ish ? The SMTP and POP protocols weren't ratified for commercial use until' 95 ?
I was using email at a time when the four ITV companies that lost were still broadcasting.
I have wondered if they had assigned themselves URLs. I was verbally informed that TV-AM had one. The .uk domain name has been in use since 1985.
.uk domains (such as
www.tvforum.co.uk) were introduced in 2014. Prior to that there were actual sites (NHS being the typical example) but they were very much the exception to the rule as they predated 1996 or whenever Nominet was founded.
Prior to 2014 the only way of getting .uk anything was typically (but not exclusively) .co.uk. This was pretty much the standard so if any UK company had registered an internet presence it would almost certainly have been .co.uk.
Some of the former ITV company sites are listed in the WHOIS as being registered before August 1996 so its plausible they'd been around a while, but I remember the main ITV site itself (itv.com) dated back to 1994 on its first registration so it may be a lot of them sprung up around that time.
As to whether TV-AM had a website or at least a URL... While the internet as we know it today dates from 1989 and the first email dates from the 1970s, I don't believe it was mainstream enough in 1991/2 to justify setting one up.
It was certainly available via the likes of Compuserve and AOL back in the days where you paid for the call AND the internet service but as I said earlier in the thread the internet didn't really take off mainstream until the likes of Freeserve launched. So while it may be plausible TV-AM had a URL in practice it was probably pointless at that point in time.
