From commando.com, this is Commando on demand, where we talk to the industry movers and shakers to keep you up to date on everything digital.

We'll get started in a moment, but first, we'd like to recognize and thank our partners who help make these Commando on Demand Podcasts possible.

Hey. possible. Hey guys, it's Mike James in for Kim Commando again.

Now, a lot of us who listened to Commando on demand grew up in a time when music

wasn't very portable.

You remember, we had vinyl records and cassette tapes and eight-track players,

but the so-called portable players were big, bulky, and required a power outlet or even batteries that didn't last very long.

The idea of making music portable is nothing new.

In fact, in 1954, a company called Industrial Development Engineering Associates, or IDEA, Idea, Bright Idea for a company,

released the first ever portable transistor radio for consumers.

Now, for its time, it was small.

It was about the size of today's smartphone, but a little thicker, and it was a great advancement for the music industry.

It sold. Now, get this. It was about $50 per radio, which is about $320 in today's dollars.

Now, keep in mind, the transistor radio depended on radio frequencies that were picked up by

antennas. If you were on the move, you were constantly adjusting your antenna.

More than 10 years later, Phillips released the first ever cassette tape. If you're over 40,

you certainly remember how much they dominated the music stores and industry for the next 20 years.

Here's a fun fact, cassettes weren't initially intended for music lovers.

They were sold to college students who could record their classes.

Now, of course, we can't talk about cassette tapes without mentioning at least the Sony Walkman,

first released in 1979.

Now, I remember being fascinated with the Sony Walkman.
