Thanks for reminding us of this simple, important fact, Al. Analog has not really been killed or scrapped. The systems we nickname 'digital' only look like streams of ones and zeroes when viewed at signal processing time scales. At smaller time scales, which are always of interest when we consider the economics of distributing those signals, they are really analog.

Of course, when a lossless, zero-delay, zero-cost power switching device is invented, linear (analog) power circuits will be obsolete. We are not there yet.

I used to tell my kids that some of the old shows were in B/W because colors hadn't been invented yet ...

Although I do remember when a cousin got a color TV - it was great to go over and see some football, expecially when one of those red teams like Nebraska or Oklahoma was playing.

I also remember going with my dad to the hardware store to check whether tubes were burned out or not.

In the summer of 1968 we got a color TV.

I immediately watched Curt Gowdy call a baseball game on NBC Sports "Game of the Week". The grass was green, really really green.

I still remember that game. I think it was the Yankees playing someone, don't remember who.

I'm probably going to make somebody feel old right now...

before my mom got a color tv, she didn't understand the big deal with the Wizard of Oz...

Our first color TV was the Heathkit we (kids) built in 1973. Still have it...it still works....

Ahh Heathkit. What a shame they are gone

If you want to watch some analog TV, come up to Canada... we're not switching over until August 2011.

But in the big picture I wonder what format "television" will take in the next five to ten years. The improvement in streaming video over the internet that I have seen over the past five years leaves me wondering how cable, satellite and broadcast TV companies are going to react to the availability of on-demand streaming HDTV... which, if not quite a reality, soon will be.

It will be exciting to see all those TV channels re-purposed to wireless communications, though. It is amazing how much digital data can be packeted down an old NTSC channel.

While I write this, a Heathkit HW101 and matching speaker with HP13B power supply sits on my right and a SB634 Station Console sits on the left with an HW-8 and some test gear is looking down from the shelf behind me.

Great photo, Al!

What? You mean the world is really....analog? <gasp>

Oh Nooooo
