Minitel "saved" by hackers?
by Arun Mehta 17 Dec '03

17 Dec '03

I'm reviewing "Cultures of Internet: Virtual Spaces, Real Histories, Living Bodies" edited by Rob Shields. Chapter 2, "The Labyrinth of Minitel" by Andre Lemos tells a fascinating story, after you get past the verbiage in the introduction (sample: "If modernity refused the artificial, and deepened separations and dichotomies, postmodernity tries to surpass well-established dichotomies, not in the dialectical sense through sublimation and synthesis, but more in the direction of making a place for dialogical complexity"). This may be old hat to cypherpunks, but it seems that the system, conceived as a videotex system, was hacked: "At the end of 1981 the messaging software ... was pirated by some users planning to communicate between each other in real time. Through this detournement -- literally, a 'hijacking' was born the messagerie." These included games dialogs in real time and postings. Soon there was the "messagerie rose", the sex stuff -- which generated most of the revenues. As Claire Ancelin notes,"the public has not hesitated to manifest tastes often opposed to those foreseen by experts, this public has not hesitated to make a serious information tool into a frivolous communication tool." So, shocked by this, what does the government do? Being unable to distinguish between different kinds of messageries, the government put a 30% tax in 1989 on all, and raised it to 50% in 1991! No wonder the Internet is gaining rapid popularity in France. My questions: 1) are any of those 1981 French hackers on this list or known to people here? 2) I checked out "Minitel history" on Alta Vista, and since my French is very modest, downloaded http://www.dlib.org/dlib/december95/12kessler.html, The French Minitel: Is There Digital Life Outside of the "US ASCII" Internet? A Challenge or Convergence? by Jack Kessler, and http://tklab6.informatik.uni-bremen.de/nii/Conference/Abstracts/berne.html THE MINITEL SUCCESS by Dr. Michel Berne. Surprisingly, neither mentioned the 1981 hijack. Can anyone suggest better references? 3) Kessler raised a controversial point: "Centralized control -- its political as well as its social and economic manifestations -- is relatively untested. Some fans of the Internet even deny the possibility of centralized control in their version of "Cyberspace". Yet such control is the single greatest issue of networked information to many Asians. Minitel's approach, which is so different from the Internet's celebrated de-centralized structure, provides useful comparisons for both systems to consider. ... The question for networking's next generation is what will scale up for Asia? To meet this challenge, some "convergence" -- some pooling of talents and approach, combining the sophisticated with the simple, the academic with the commercial, the decentralized and chaotic with the centralized and bureaucratic and controlled -- might not be such a bad idea for both the Internet and the Minitel to pursue now." Do you know of any country in Asia or elsewhere favoring the Minitel "centralized and bureaucratic" model over the Internet?

-----BEGIN PGP SIGNED MESSAGE----- The Digital Commerce Society of Boston (Formerly The Boston Society for Digital Commerce) Presents Fred Hapgood Digital Commerce: Living Room ExIm, Retail Replacement, or Mail-Order Redux? Tuesday, February 6, 1995 12 - 2 PM The Downtown Harvard Club of Boston One Federal Street, Boston, MA Fred says: >So far Web commerce has largely been a speciality export story. >(www.activmedia.com says that web commerce is half exports.) This >reflects the obvious strengths of the medium: webstores are >globally accessible and can support information resources to any >depth customers require. > >However, the meat and potatoes of the $2 trillion American retail >market lie not in specialty exports but in geographically >structured markets built on access to local traffic and >characterized by low-information transactions.

Fred Hapgood has written on internet commerce for _CIO_ and _Webmaster_ magazines. He has written on associated subjects for _Wired_ and _Inc-Technology_. The February talk will be based on research for an article on the web and franchising. This meeting of the Boston Society for Digital Commerce will be held on Tuesday, January 2, 1995 from 12pm - 2pm at the Downtown Branch of the Harvard Club of Boston, One Federal Street. The price for lunch is $27.50. This price includes lunch, room rental, and the speaker's lunch. ;-). The Harvard Club *does* have a jacket and tie dress code. We need to receive a company check, or money order, (or if we *really* know you, a personal check) payable to "The Harvard Club of Boston", by Saturday, February 2 , or you won't be on the list for lunch. Checks payable to anyone else but The Harvard Club of Boston will have to be sent back. Checks should be sent to Robert Hettinga, 44 Farquhar Street, Boston, Massachusetts, 02131. Again, they *must* be made payable to "The Harvard Club of Boston". If anyone has questions, or has a problem with these arrangements (We've had to work with glacial A/P departments more than once, for instance), please let us know via e-mail, and we'll see if we can work something out. Planned speakers for the following few months are: February Fred Hapgood Freelance Author March Glenda Barnes X.9 Electronic Commerce Security Group April Donald Eastlake CyberCash May Perry Metzger Security Consultant and Cypherpunk June Dan Shutzer FSTC July Pete Loshin Author, "Electronic Commerce" We are actively searching for future speakers.
