Kinda hoping that Netflix's new "we'll ban you if you watch the Netflix account you paid for outside of your home too much" story turns into a "New Coke"-style business school case study in how to do something totally stupid that pisses off your most loyal customers, and leads Netflix to reverse course quickly.
@mmasnick Kinda reminds me of how in early public Internet days some big ISPs tried to charge separately for every device hooked to the Net, and even tried to ban NAT.

@lauren @mmasnick The phone company did this too. First you had to rent phones from them, then pay for each device connected. One of the ways they found "illegal" phones was the voltage drop from the number of phones that rang for an incoming call. So phone makers added a switch to turn off the ringer.

First phone mute button was for pirate phones.

@kevin @mmasnick By the time there were phones being sold publicly the major telcos had long since stopped counting subscriber phones. The traditional method for blocking the count of extra phones while still permitting them to ring was to put a neon bulb in series with the ringer. Or uh, so I've been told.
@kevin @mmasnick Oh, by the way, their phone counting did not rely on voltage drop during ring. They used a capacitance check, usually late at night. Sometimes this would result in a minor ringer bell tap.
@kevin @mmasnick Coincidentally, I was watching old episodes of the "The Saint" recently (one of my favorite old shows) and in at least two they used bell tap during dialing on a different phone in the house as a plot point revealing that the other phone was being used to make a call.
@lauren @kevin @mmasnick
In 1970s Berlin, when you picked up one phone an indicator would flip red on all the other extensions and they would go dead until you hung up the first phone. I was told it was an anti-eaves dropping measure.
@JRBuckley @kevin @mmasnick I've never heard of that. Unless there's a bypass, it also means you couldn't add someone onto an extension during a call!

@lauren @kevin @mmasnick
Exactly, only one extension could be used at a time.

Admittedly, I was 10 when I first encountered this and it was in locations controlled by the US Military (offices and off-base housing) in West Berlin, so I don't know if this was a standard thing or if I misunderstood its purpose, etc. I never saw it anywhere else after that or during the 12 years I spent in Southern Germany in the 1980s-90s.

@JRBuckley @kevin @mmasnick Thinking it was a military thing most likely.
@lauren @JRBuckley @mmasnick this is like the 4 extra buttons military phones had.
@kevin @JRBuckley @mmasnick That was AUTOVON. Fourth column red buttons: FO - F - I - P (flash override, flash, immediate, priority).

@kevin @lauren @mmasnick

These phones looked like the standard gray German phones of the day except for the mechanical indicator. Now that I'm wracking my brain over something I haven't thought of in close to 50 years, I think some of our German friends had phones like these, too.

It may have been a Cold War/Berlin thing.

@kevin @lauren @mmasnick And if someone left a phone off the hook and you needed urgently to contact them, you could ask the operator to send a howl down the line - their home would suddenly fill with this eerie howl
@sinabhfuil @kevin @mmasnick I've never heard of an operator initiating the howl. For sure many systems would run a howl for a relatively brief period if a phone was left off hook. Maybe some even kept it going until the handset was hung up again. Though smaller systems certainly could vary in practice.
@lauren @sinabhfuil @mmasnick Is the howl the strobing tone you'd get when you left a handset off hook? I remember us getting the North American tone on the Wikipedia page, but never heard it referred to as a howl. Jeez, I haven't heard that in forever.

Off-hook tone - Wikipedia

@kevin @sinabhfuil @mmasnick There are different ones. Some sound like sirens up and down. Others are loud BLEEP BLEEP BLEEP tones at a high rate.
@kevin @lauren @mmasnick
My grandfather built his house and it wasn't until the switch to touch tone dialing that the Phone Co realized that he'd installed a phone outlet in every room and had a dozen phones (not all plugged in at the same time). I don't remember exactly what happened, but there was drama.
@lauren @mmasnick I just set up internet less than a yr ago and they asked how many devices I had. Litterly laughed and said IDK.
@alexisdyslexic @mmasnick They want to sell you a higher speed connection.
@lauren @mmasnick think I had already signed up for the fastest they had.
