Ringing in Changes

I was getting a kick looking at a page from the Smithsonian Institute on how information technology has changed over the past 150 years.

To be honest, when I think of information technology, I really don't think of the telegraph or the telephone.

But maybe I should. The means of communicating over long distances, aided by electricity and wires, are the roots of information technology.

When you look at the pictures, it's easy to forget that these devices cause profound changes in society as they were introduced. But some of it didn't happen overnight.

I found a much more detailed view of telecommunications, which goes from the 1820s to today's mobile phones.

It's become pretty common to see people walking down the main street of my town with a mobile phone pressed to their ears. It wasn't as common in 1879, when David Hughes received the first radio/telephone call.

Yes. The mobile phone is now 125 years old. Not what you'd call an overnight success. Wonder what David Hughes would think of ringtones.
