Sony went through a stage where their stuff was the best in the business-particularly in the TV Broadcast field.
Tektronix tried to break into the Precision Picture Monitor business with their 650 series,which,when they worked properly,made many of the previous manufacturer's efforts look sick.
The problem is,they didn't work properly for very long!
When Sony came out with a Pix Monitor which fitted into the same space,it not only worked better than the Tek ,but it also continued to do so for years.
TV Stations are not dumb,they bought Sony!
Studio type VTRs were almost exclusively Sony for many years.
In TV transmission,the same story applied to NEC.
One place I worked at had older Siemens TV Tx as well as newer NECs.
If you held your face just right,& spent an enormous amount of time,you could get the Siemens further within spec than the NEC.
Come back next week,& it would have drifted out of spec.
Come back 6 months later,& the NEC would have hardly budged.(The older NECs were just as good!)
And the documentation--
NEC was in pretty good English,on glossy paper,with full circuit diagrams & descriptions of circuit operation.
The Siemens handbook was about 5th generation photo copy,with the English translation written by somebody's secretary who had taken a few English lessons.
Now,of course,Sony & NEC have thrown that great tradition away,& badge engineer Chinese & Korean stuff!
How the mighty have fallen!
