My grandparents had a TV from the 1970s, possibly 1960s, that would automatically adjust the color balance to match the room lighting. It really is an old idea.
Shipped on LCD TVs from multiple manufacturers in 2008, too: "new TVs automatically tweak their on-screen colors to complement say, the orange glow of incandescent lights in the evening or the bluish tint of midday sunshine." Six months before F.lux shipped.
