Back in the early 1990s, when the DSO's record length wasn't deep enough (unless one paid a fortune) I was also designing analog-TV baseband circuits.
To properly see the chroma burst and static pattern in the active video, one had to use an analog scope.
Not any scope, but one which had advanced TV triggering capabilities, i.e. trigger from a specific line. But the resulting display was very dim.
For that reason, Tektronix and other manufacturers also sold waveform monitors, which were specialized scopes for the purpose of viewing analog TV signals, see attached image.
Then Tektronix came out with the VM700, one of the first all-digital waveform monitor.
Ever since I first used the VM700 in perhaps 1995, I have never again used an analog scope.
