Minitel
（重定向自Teletel）
The Minitel was a Videotex online service accessible through telephone lines, and is considered one of the world's most successful pre-World Wide Web online services.
The service was rolled out experimentally in 1978 in Brittany and throughout France in 1982 by the PTT (Postes, Télégraphes et Téléphones; divided since 1991 between France Télécom and La Poste). From its early days, users could make online purchases, make train reservations, check stock prices, search the telephone directory, have a mail box, and chat in a similar way to that now made possible by the Internet.
