It's Always a Good Idea to Attach the Head Set (1921)

Over at Allan Holtz's comic strip blog, the excellent (but mischievously named) Stripper's Guide, there are three panels of Today's Hook-up from the early 1920s . This was a daily cartoon by J.C. Henderson that sent up the new craze for radio.

The radio aficionadoes in Today's Hook-up are obsessed with pulling in that signal (hard work at times, apparently) and checking those program guides, to the point of neglecting everything else.

You can't help being reminded of the Internet, especially when it was just taking off and people were struggling with setting up their new computers and connections and, yes, getting a bit obsessed in the process.

There's a frustrated listener in the first panel who has 'worked and worked for over an hour' and 'didn't get a thing'. He's forgotten the classic first step of any tech support protocol: First and foremost, check to make sure all cables and cords are plugged in and firmly seated.

Or, as the caption says, It's Always A Good Idea To Attach The Head Set.
