I wonder what the turning point for Sammy really was? Sony's trajectory is well documented, but Samsung just kinda happened as far as I'm concerned. Toshiba and Panasonic et al sort of fizzled out and the Koreans took over somehow. Seems to just be dogged perseverance and investment by Samsung.
Easy. Flat panel TVs. As analog CRT TV sets started to disappear, the old guard premium TV makers could no longer justify the price premium on their televisions. A midrange LCD TV offers 90-95% of a premium branded TV's picture quality at half the cost. A well made budget TV gets you 80+% of the PQ of a premium TV for 10-25% of the price.
Mass producing a really really good CRT TV with excellent PQ is hard. Doing the same with an LCD is easy in comparison.
LCD TV's basically allowed everyone to instantly catch up to Sony. And when (to non-videophiles) a 500 USD LCD TV looks just as good as a 2000 USD LCD TV. They go with the cheaper one. Hence, the meteoric rise of Samsung, LG, and Vizio. While Sony, Sharp, Toshiba, Pioneer, etc. all started to drop.
Money from the sales of budget and mid-range sets then allowed those other players (if they invested wisely) to venture into the Premium TV territory. Their advantage, however, was they weren't reliant on the premium market for profits. They had a well established profit base to draw from in the midrange and lower. Not something that the Japanese TV makers could fall back on to keep their TV divisions profitable.
As well, that whole budget price range = 80+% of premium PQ is also why the Chinese players are starting to gain some significant ground in the TV market. They can make TV's even cheaper than Samsung, LG, and Vizio. Although quality on the Chinese branded TV's can be hugely variable.
Hence, why LG is so invested in OLED. If they can manufacture them economically enough they'll not only be selling their own sets, but providing the panels for most of the world's premium TV makers. They are almost there, but not quite yet. They've built another manufacturing plant for producing OLED panels, but have run into some problems that are causing delays.
