TV manufacturers, too, don't want me to forget whose brand I own. They prefer to put their logo in a way that contrasts with what is around it. Phillips, Toshiba, and Sharp, for example, put their logos either in white or silver against a black background, or in black against a silver background:
Panasonic, at least, offers some sets with a silver logo against a silver background, which makes it a tad less obtrusive.
I'd be delighted to find a television set that didn't insist on advertising itself every time I look at it. Does any major manufacturer have such a product?
