43 1/2 years ago ..... wow!
I saw it/lived it when it happened 'in real time'...
On Jeanie Dr. off Willow Pass in Concord Ca., my 2nd house
I wanta' say; it was midday, mid week (?) something like that...
My nephew worked for Concord Cable/Comcast
& he installed "a pirate box" (it was like just cut the orange wire)
like 2 days prior, & I had every channel there was...
He told me about it,
Out here, I remember, mostly all the 1st Music TV/videos
was mostly Jazzercize videos
close up of babes bent over/crotch shots,
set to rock & roll 
later
Ted Nugent w/scantly dressed young babes (great music),
Van Halen/David Lee Roth bouncing around, Eddy with some great licks
AC/DC Angus Young/Von Scott (great tunes),
Kiss was a spectacle, a huge favorite
ZZ Top & their cars, Bob Seger (2 other great ones)
The Nack, Dr. Hook & Medicine Show, Phil Colins, Foreigner, The Cars,
Devo, Rossington Collins Band, Blue Ouster Cult, Queen - We are the Champions
Molly Hatchet (southern rock), Aerosmith, & Boston (those were great ones)
Twisted Sister had some funny videos, actual/acting plot to music...
Dire Straights, Money for nothing MTV, 1985-ish (?)
Lots of 'Hair bands' coming in then too
I remember Lisa Kenndy as a MTV-VJ 1990 (a bit later, she's 52 (?) born in 72'),
from Oregon, lady from Fox New now
even KFRC AM, was still big deal in the East Bay Area too, in 1981-ish
