Welcome to the first week of the Tech for Techies class! To learn about where we are going we have to look at where we have been. This week we look at the history of broadcasting that preceded podcasting. We also take a moment to look at a bit of "audio snake oil" when it comes to the physics of cabling.
There is no homework for next week with the class. That won't always be the case, though.
