It's wierd how Vizio kinda popped out of nowhere and got pretty known pretty quick for a consumer electronics company. They are kinda like how Amped Wireless!!!!! is.
Actually, it's amazing what quality inexpensive labor will get you as a brand.
That was, in fact, how the original Japanese electronics firms (and their ROK/South Korean successors) built their reputations. (Examples - Sony, Mitsubishi, Samsung, the Hyundai Group.)
The latter three, in fact, are conglomerates in the *old RCA* sense. (RCA, for the younger Neowinians, stands for Radio Corporation of America, and was the *second* company forcibly broken up under the hammer of the Sherman Anti-Trust Act - the first was the *Standard Oil Trust*.) The forced breakup of RCA, in fact, predates World War II. Even after that, RCA still remained a mini-conglomerate - manufacturing everything from radios (and later telelvisions, including equipment used in their respective broadcasting) to carpets. (Carpets? Yes - Mohawk Carpets was at one point wholly-owned by RCA, as was - shockingly - Hertz Rent-a-Car.) Mitsubishi is basically RCA writ small - in North America alone, they are in fields as wide-ranging as electronics to food - for both pets and people. (In Japan, they are also in the banking and insurance businesses.) Samsung and the Hyundai Group are Korean versions of the same *keiretsu* as Mitsubishi; while they overlap in electronics, Hyundai was oddly enough chased *out* of the heavy-equipment business in the ROK over a corruption scandal involving rigged bids (the victim was, amusingly, US-based Caterpillar) and wound up selling that business to Volvo.
Vizio has indeed shook up the TV market (they are still around as a TV manufacturer; among private brands they build for are Best Buy's Insignia and Dynex). While ROK-based Acer Group has somewhat moved upmarket, there is still a need for a value-brand at the low end.
