Why the static between changing channels. Analog TVs would change channels instantly.

In my experience, it was fairly common for there to be (as an example) a channel 3 and a channel 5 but no 4, so if you were flipping through the channels on certain TV's you'd see static.

Yes, in broadcast (over the air) TV, only every other channel was allocated in a given area. That's why most devices that connected to a TV (computers, VCRs, etc.) could use either channel 3 or channel 4 because one of the two would be unused.

There were some exceptions, though, as the VHF TV channels aren't all contiguous. In North America, there's a gap between channels 4 and 5; and channels 6 and 7 are separated by the bands for several radio services (FM, aviation, amateur, and marine).

Hm, didn't know that. But I still remember the channels we had when I was a kid:

2, 4, 6, 8, 10, 13, and UHF 30.

I also remember that depending on the radio, you could sometimes pick up the audio for I think VHF channel 6 at the low end of the FM dial.

ISTR we had 2,4,5,9,11, and 30 (UHF). Channels 2-5 were ABC, CBS, and NBC. Channel 9 was PBS, and 11 and 30 were local stations that weren't affiliated with any of the major networks.
