Like I said, it spread around the world very quickly.

The BBC started broadcasting in 1922.

Australia's first radio station, 2SB, which is now ABC Sydney, they started in 1923.

Canada got its first one in 1932, XWA out of Montreal.

Yeah.

It was just like the Internet.

It's not like it was just one country.

It was everybody who got involved because it was a humanity-altering invention.

yeah for sure uh by the late 1920s um the major networks had launched uh and you know these were radio networks nbc and cbs um these were international broadcasts from the united states all over the world and you know they worked by you know you had to have a receiver so early on uh you know vacuum tubes um worked with radio receivers connected to loudspeakers and that's how you could hear things later on transistor radios came along

And that's what really changed the game, because that's when it was like TVs for the olds.

The young people were had these little radios in their pocket and then they started, you know, putting radios in cars.

But it's funny to think about a time when like, yeah, TV is outdated and we want AM radio in our pocket.

And then it came roaring back eventually.

Thanks to L.A.

Law.

You mentioned something that I think is worth calling out, too.

You mentioned that there's a speaker that converts that sound signal back into actual acoustic sound.

They weren't headphones.

They were speakers.

So that meant that early radio was a thing that the family gathered around.
