Quote of the Week

'If all your friends jumped off a bridge, would you jump too?' 'Oh jeez. Probably.' 'What!? Why!?' 'Because all my friends did. Think about it — which scenario is more likely: every single person I know, many of them levelheaded and afraid of heights, abruptly went crazy at exactly the same time… …or the bridge is on fire?'

Randall Munroe (xkcd)

S: Hello and welcome to the Skeptic's Guide to the Universe. Today is Wednesday, September 24, 2014 and this is your host, Steven Novella. Joining me this week are Bob Novella...

B: Doing good, Evan.

J: All right, yeah.

This Day in Skepticism (0:29)

R: Happy birthday to the answering machine, which was invented on September 27, 1950! Now, for the bulk of our audience, I will now describe what an answering machine is.

(laughter)

R: An answering machine was a little box that you used to plug your phone in to, and when you weren't there at home, because you couldn't take your phone with you back then, the answering machine would pick up and people would leave messages, and it was very exciting. We would leave prank messages sometimes, we would have prank recordings on our answering machines.

J: Yeah, you mean the outgoing message was the prank too.

R: Yeah. Yeah, it was a time of pranks.

E: Oh, I hated that one where someone would say "Hello?" and then wait a few seconds (you're speaking to the answering machine) and then you say something and it says "Oh yes, hi, how you doing?" and then another pause and you think you're speaking to someone but it's a damn answering machine. Hated it.

J: (laughs)

B: And don't forget, this wasn't saved to a hard drive or a solid state drive, this was like a cassette tape that all of this action is happening on. (laughs)

E: I bet you in the 50's it was some reel-to-reel device that took up three rooms like UNIVAC or something.

R: I found on a website that the answering machine was invented on this day in 1950, but I've also found elsewhere that the first commercial answering machine went on the market in 1949 (laughs), uh, and that was called the Tel-Magnet. And the problem is that I'm in the midst of moving house, and I could not suss all this stuff out before we'd started this recording. So I'll mention that and I'll also mention--and I think this came up in a previous Science or Fiction years and years ago or something[link needed]--but, really, the first answering machine was invented in 1898 by a man named Valdemar Poulsen and this was basically a recorder that was used for recording conversations on the telephone. And it was the basis for what eventually became the mass-produced answering machine. So...

S: Right.

R: ...a dubious day in history, but, you know, I'm going with it.

E: (laughs)

S: But the first, from what I'm reading, the first commercially successful answering machine was the Ansafone in 1960 in the United States. Yeah, the Tel-Magnet, 1949, was recorded a message on a magnetic wire...

B: Whoa.

S: ...that sold for $200...

E: That's worth it.

S: ...but was not, not a commercial success.

R: You know, I remember when there was a short period where cell phone companies would charge you just for voicemail, for like a dollar a month...

S: Mm hm.

R: ...and I just found that ridiculous (laughs). I can't even imagine a $200 answering machine.

S: The telephone is definitely one of those things that has changed consistently over the years and you could, like, tell, like you can date a movie by the phones.

R: Oh yeah, absolutely.

S: Yeah, pretty well. Even, as well as you can, say, with computers, you know.

R: I've done that several times where I'm watching a film and, you know, sometimes a film will be set in a certain period but they don't come out and tell you right away...

E: Mm hm.

R: ...like a lot of indie films will do that, and I'm really just always looking for telephones so I can figure out exactly when it's supposed to be.

E: Within a few years accuracy, yeah.
