Heh yeah, I know what you mean. It's also just really interesting to me how analog video degrades over bad transmissions[1]. With digital video, you usually don't get much more than just a disappearing stream, but analog video has/had all sorts of different failure modes, and they revealed a lot about the underlying encoding. And they all had their particular "look and feel" to it.
There was also a third color modulation scheme, SECAM, which was very different from NTSC/PAL (PAL is really just "NTSC 2.0"). It added the two color signals using plain FM. When degrading, it gave rise to something sometimes called "SECAM fire", and anyone who spent some time in France back then, me included, might subconsciously remember it: https://www.scheida.at/scheida/TV_SEITE/SECAM_Screenshot_Secamfire_lowRF.jpg https://www.scheida.at/scheida/TV_SEITE/SECAM_Screenshot_Sec... http://www.scheida.at/scheida/TV_SEITE/SECAM_Screenshot_Secamfire_Scart_Insert.jpg http://www.scheida.at/scheida/TV_SEITE/SECAM_Screenshot_Seca... (Those pictures are not from me, just found on the Internet.)
To the casual onlooker that probably just looks like noisy pictures, what's the big deal... But to me it's interesting because the noise is different.
[1] Of course, my picture is not a bad transmission, just bad decoding.
