It’s a joke… https://xkcd.com/378/

I believe you’re thinking of France’s minitel (wikipedia) . I never used or saw it myself. Living in a neighboring country, i did see quite some adds mentioning it on their tv stations. Trente-six-quinze-minitel! Club Dorothée FTW! :)

I’m here just to join you shouting out. Great peace of software.

We’ve even been doing that for thousands of years!

I’d read more of this.
