IRC was pretty widely used back in the day too, and it was and still is text-only. There have been a number of non-text replacements for IRC (SecondLife being the most successful) but most died off. IRC's grandchildren, Twitter, SMS, all of the instant messaging and chat services, are all still text-only or close too it.

OK, but I feel the need to stress that when I wrote "text only", I was referring to the user interfaces.

(And the reason user interfaces are relevant here is that telnet was the main way to export user interfaces over the internet in 1992.)
