The Minitel is a Vieotex online service accessible through the telephone lines, and is considered one of the world's most successful pre-World Wide Web online services. It was launched in France in 1982 by the PTT (Poste, Téléphone et Télécommunications; divided since 1991 between France Télécom and La Poste). Since its early days, users could make online purchases, make train reservations, check stock prices, search the telephone directory, and chat in a similar way to that now made possible by the Internet.
