I don't think you can write down the full credit card number either any more - if you store it it has to be encrypted and stored to financial industry standards (read $$$). So they were risking their business, or at least $100k audits and monitoring, because their telco didn't want to replace some copper wires.

Western Europe, too. Even England, which was the best off, didn't privatize until the mid 80's. I no longer remember the details, but there were elaborate schemes before that in which private companies made money by trunking calls from one place in England to another through New York, because anything routed through the US was cheaper. The employees were government employees, too, so Lily Tomlin made fun of Ma Bell operators but even our regulated monopoly was a delight by comparison to a government bureaucracy. My mother said that the first time she got connected to a wrong number in Germany, she called the operator and explained what had happened. The operator said, "I did *not* give you a wrong number," yanked our plug, and wouldn't permit us any phone calls for the rest of the day. :-) When we were living in Spain, the common phone conversation initiator was a loud, "Oiga? Oiga? Digame?" ("Hear me? Hear me? Say something?") I'm sure things have improved all over Europe, but a lot of that is because the governments don't own the cell providers. Most folks here have had decent phone service their whole lives and only know it wasn't always that way intellectually. My grandparents' phone number was "1." They had the first phone in Haynesville, LA. Here, when I moved out near Erie, in the mid-70's, we had to use an operator to make local calls.

Moreover, local calls for a long time were charged just a single "token" (100 liras + VAT, or about $0.05 + taxes), regardless of duration. Long distance were charged more, probably too much, but I did not have persons to call at a long distance, so I don't remember the details. My parents did and they did not complain about anything, other than sometimes the price (but there was really no comparison for a similar service, so it's hard to argue it was too much, and how much of it was paid by the taxes? I dunno and don't care to research) In the early 90s, the price structure changed substantially, in preparation of privatization and in response to the spreading of BBS first and dial-up internet later (local calls were charged by time, instead of a token fee). At that time I started caring about long distance calls too, and even if I don't remember the price from the top of my head (learning new facts is easier for youngster), it was quite high, compared to what happened a few years later. In fact, allowing private actors into the field in the late 90s did bring the price down quite substantially, but qualitatively speaking (both for voice and for modem connections) I did not notice any difference whatsoever, other than the steady improvements in computer's modem speeds (when I bought new modem models -- hard for me to tell if the newer model would have been equally better on previous years' lines and switchers) I never spoke to an operator in my life and the first phone call that I dialed myself was probaly around 1979. FWIW, in Italy, cellular telephony also started as a gov't monopoly in 1990, and has been such for more than half a decade before being opened to the private sector (with just a single private company, competing against the "government") in the late 90s. According to wikipedia.it, it wasn't until 1997 that the competition was able to get a decent enough number of customer to be called business. On Mon, May 18, 2015 at 1:59 PM, Jeffrey S.
