Their electronics were top notch and when I said nobody cared about their TVs/VCRs I meant, as much as the 11-30 demographic would have wanted them most would choose the cheaper option assuming they had a choice in the matter.
Walkman and PS1 were the exception. There was always a budget Walkman and the PS1 was the cheapest console available with the cheapest games and it could be easily pirated and also had the value of being CD/VCD player. It also had much more accessible controls and was arguably a better successor to the SNES than the N64.
The Sony name was an advantage to them starting out with the Playstation. Remember Phillips had their own CD-i system about the same time. It was a piece of crap. SNK? Who are they? Having Sony's name on the system means it has some respect and name recognition even when they didn't have any history on the console market.
Sony's name was also an advantage with PS3 vs XBox 360. The latter console was known for the RROD. Sony is known for quality electronics. That branding has always helped them. That may not make a difference with everyone, but for some people it matters a lot.
