Can you podcast physical things?
Most people think of podcasting in a fairly limited sense. – for example, radio shows that you can download automatically.
We’ve always had a broader view, that podcasting was the publishing of downloadable files with an RSS 2.0 news feed. With that in mind, you can use podcasting to automatically stay current with all types of files, through audio podcasting, video podcasting and, more generically, document casting.
In each case, podcasting is being used to make it easy to get the latest version of something – whether it’s a radio show, a song download, a new video or some other file.
Why not podcast physical things, though?
We’re moving into an era where on demand manufacturing is becoming commonplace, and DIY’ers are buying 3D printers that can print actual physical objects on demand. The children’s toy, above, is an example of what a company called Ponoko does – on demand manufacturing.
This technology is very expensive now – but the 300 DPI Apple LaserWriter cost $6,995 when it came out, and now companies give high-resolution printers away to get you to buy ink cartridges. On-demand object printers are going to rapidly become affordable, too.
Is there any reason podcasting can’t be used to distribute the latest versions of files that create things, just as easily as podcasting is used to distribute the lastest versions of an audio show?
What do you think? Futuristic or just fantasy?










Good news for new media publishers – Internet media is rapidly becoming the biggest channel for advertising.
