What Puma said about shortwave radio.
There were a lot of shortwave/ham radio fans across the world, certainly that generation's version of Internet addicts and tech geeks.
This scene from a 1939 Andy Hardy movie drove home to me of how far we've come. The stuff you might find of interest is 1:30 seconds into the scene. You can see how things might have been done back in the day, and the kid mentions contacting a guy in Australia. THAT was cutting edge tech back then, worthy of respect!
Now, we'd use a cell phone or the Internet with a webcam and complain about the service.
Of course, some kids built their own radio sets. The ads in the backs of magazines weren't always about X-ray glasses and slapping on 50-lbs of he-man muscles using the Charles Atlas Method.
You might let yourself become addicted to old movies. They do leave a record about ordinary things like phones, stores, cars, roads, fashions, and tech. I find myself ignoring the plot and taking notes on the street backgrounds and such!
I recall my mom was on a party line in the 50s-60s with another person to save money, but she never could make or get calls because the gabby neighbor tied up the line or she'd want to chat with Mom, who was never interested in making friends. She finally bit the bullet and got a private line, Crestview 4-2900, or CR4-2900 as you'd see it on the thing in the middle of the rotary dialer, typed in pica by someone at the phone company, sometimes written in ink by hand.
I suppose the equivalent today are those phone party things of those TV ads where "ladies are always talk for free" and guys pay a dollar a minute or more. The ads always show hot chicks with time to waste on the phone. I rather expect the reality looks somewhat like my avatar.
The phones were totally controlled by the phone company. They installed the phones,
owned them, and dictated where in a house to put the phone. Having more than one phone in a house was unheard of! Why would you need more than one phone? Well, that will cost you! Next thing you know they'll want a second bathroom!
Usually there would be a niche in the hall wall where the phone would be parked on a little shelf, with a second shelf under it for the phone book. Here's a 1920s "
gossip bench" that the better houses had.
Forget moving to another room for a private chat. Our phone line was *just* long enough to reach the bathroom. You couldn't buy longer cords, you had to have a phone guy come in and install one for you. Get the checkbook ready, too.
As a pre-teen I recall putting the phone on the floor, the connecting line from the wall wasn't long, so the phone stood on end, and I stretched the receiver cord to my room. If I lay on the floor I could talk, but my parents could still listen in, dammit.
Wire-taps on phone lines were possible in the 30s. Herbert Hoover turned a blind eye to the Chicago branch of the FBI when it came to tapping Al Capone's lines. It was illegal, but Hoover wanted results.
And yes. Phones were HEAVY. They were good blunt force trauma weapons in some murder mysteries if you could lift one. No lightweight plastic, they used
bakelite and steel.
Later models might have a ringer volume control, otherwise they were set to wake the whole house. I remember putting paper between the striker and the bell to mute things. If you wanted it off, you took the receiver off hook and waited for the buzzing to stop. In a Thin Man movie, Nick Charles stuffed it in a drawer.
