I used to be a project engineer in the TV industry and for reliability I'd choose Panasonic over Sony all the time.
Sony claimed to have the features and but rarely delivered them in a way that would integrate nicely with other equipment - nor was the kit reliable, and customer service across the industry was apalling.
And I'm talking about business-critical stuff costing the equivalent of entire containers of e-bikes..
another bit of inside info is the entire "creative" industries have been experiencing harder and harder times since the dot com crash, (exacerbated by the above problems). so there is plenty of opportunity for "product placement" (i.e covert advertising) and no such thing as a impartial documentary.
