As stated by Jacquesm, Minitel slowed down Internet deployment in France. Every bank, mail ordering sellers or alike already had their Minitel "site" (in which they invested money) so jumping in the new train took time. At the end of the 90's, I had to develop a Minitel Emulator for a French bank who wanted to put PC based kiosks where people could have many informations (static coded texts) but also connect to their…
Just for the record: We had a similar experience with banks in Germany, it was called "Bildschirmtext" or "BTX". It took a long time and a lot of emulators until they finally adopted the Internet. Besides this, BTX was not as omnipresent as Minitel was in France.
"Bildschirmtext" (BTX) is almost as old as Minitel and
technically very similar, but it was largely unsuccessful
because consumers had to buy expensive decoders to use it.
The German postal service held a monopoly on the decoders
that prevented competition and lower prices. Few people
bought the boxes, so there was little incentive for
companies to post content, which in turn did nothing to
further box sales. When the monopoly was loosened, it was
too late because PC-based online services had started to
appear.
