Re: I was there too
Beat you to it, man. Born 1957, here. Watched John Glenn's Mercury flight on a clunky 19-inch B&W portable which was only portable in the sense that it had a handle on the top. A common book in many US households was the infamous troubleshooting and tube-testing guide. You could actually open up the set, pull the suspect tubes, and take them to tube-testing kiosks which were ubiquitous in many drugstores and supermarkets.
I can also remember when TV via satellite was a big-ass deal; watched '64 Olympics with the caption "LIVE VIA SATELLITE" burned across the bottom of the screen.
Color was still a big deal then, too. Even though there were a fair number of color sets in use when I was a young boy in the mid '60s, they were sick-ass expensive, and not all programs were broadcast in color; those that were, were preceeded with a little bumper announcing, for example, "the following telecast is brought to you in Living Color, on NBC".
Not much channel-hopping back then, either; changing the channel involved a major commitment to getting up, walking across the room and ker-chunking that big-ass knob.
Still, it seemed as if there was so much more cool stuff on when I was a young boy, and a teenager. At first I chalked it up to just getting old, until I started hearing more and more people far younger than I remarking that TV today sucks.
