I remember distintly, at the end of every episode's opeing monolog
"There isnothing wrong with your television...
We are controlling the transimission.
We control the horizontal... and the verticle.
We can deluge you with a thousand channels...
or expand one single image... to crystal clarity.... and beyond.
We can shape your vision to anything our imagination can conceive.
For the next hour, we will cotrol all that you see and hear...
YOU are about to experience the awe and mystery which reaches from the deepest inner mind... to the Outer limits.
MUSIC THREE BEAT END-
"Please stand by"
That last line. I remember cause it made it for me.
I find myself having to say it every time I watch one of these and the announcer doesn't say it! Shoot, to me it kinda takes something away... just those three words.
Hmph, don't know if anyone else remembers it, but it always stood out in my mind. Kinda Cool techy ahead of its time.
Please Stand by..
