Of course, thirty years ago it was H-P.
Back in the late 60's, our lab supervisor showed me a cute trick having to do with the H-P logo. HP had just bought a company that made lab power supplies, named Dynetics. The logo on the front said "dy," but if you turned the PS upside down, it was the traditional "hp." Cute.
But for scopes, you hadda go with Tektronix. I've used everything from a 512 up to the TDS2024B sitting between my keyboard and my monitor.
Have any of you guys read “Bill and Dave”? It’s a great story, but kind of sad in retrospect.
