Watch TV from the 90s and earlier

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

That depends on the type of TV! The old kind had a manual rotary switch, and you had to move through all intermediate channels regardless of whether a station was broadcasting there, so you could see static when switching.

For example, in my area, the main stations were at 4, 5, and 8. Switching from 5 to 4, I'd see no static because they're adjacent. Switching from 5 to 8, I'd see static while the knob was at 6 and 7.

The 60s, 70s, and 80s TV sets on the site are the style I'm talking about. The 90s and 2000s TVs aren't.

The best way to do it would be to use different transitions depending on the style of TV depicted. But the way they did it is not wrong for all analog TVs.

Ha! In the 80s I was the remote control. We had one of those TVs with rotary channel switch. And 7 year me had the important task of changing the channel whenever needed, and adjusting the antenna as well.
