The technologies demonstrated used the television screen as a delivery station. Although there were already computers, so-called mainframes and mini-computers, these were used in science, in financial services and in administration departments. And the PC had just been developed, but hadn't really reached the Netherlands yet. The publicity preceding the consumer fair therefore generated television-focused headlines such as 'Extra opportunities coming on television' and 'Besides television for watching, there will also be text television'.
The two services have run different courses. Teletekst has been very successful up to the millennium. As many countries like the UK and Belgium have abandoned the teletext services, Teletekst is still operational in the Netherlands. The PTT service Viditel was less successful and was operational till 1989, when it was replaced by its successor Videotex Netherlands. This service worked with a different organisation and has multiple delivery devices (television, PC and Minitel). The service got a wider usage and had. A milestone was reached in 1994 with 250.000 users and 3 million connected minutes. However, Videotex Netherlands was overwhelmed by Bulletin Board Systems (BBS) on PC and the introduction of the Internet. Videotex Netherlands was officially closed on January 1, 1997.
*Viewdata was the generic term for interactive services with teletext-like screen presentation over the telephone, which was later replaced by videotex.
