This is how little kids react these days when you show them a Walkman

July 1 is the anniversary of the Walkman, the handheld cassette tape player that first went on sale in 1979 and then dominated the music industry for decades.

Today, it's been largely replaced, first by the iPod and now by smartphones. And as it turns out, kids don't even recognize the once famous device.

The Fine Brothers have a hilarious video on their wildly successful YouTube channel that shows children reacting to the Walkman.

Some of them think it's a phone. And then they realize it's not:

They have no idea what this thing is:

And none of them can figure out how to make it work:

"So when you wanted to hear a song, you had to press the fast-forward button and just guess."

"I prefer my iPhone over this thing! This thing is so hard!"
