Samsung and Vizio have been playing a game of leapfrog the last couple of years. It seems every couple of financial quarters, the manufacturers switch between the number one and number two spots on the top LCD sellers chart. But as of right now, Samsung is king of the mountain again.

Vizio’s Q3 sales accounted for only 15.7% of the US’s total, while Samsung managed to move 16.8%. iSuppli credited Samsung’s LED backlighting push for the higher sales. LED backlight means thinner TVs. The rest of the manufacturers, LG, Toshiba, and Sony only managed a 8.1%, 7.8%, and 7.8% respective market share.

But here’s the thing, only LG saw its numbers actually increase from the second quarter of 2009. Everyone else, including the top dogs, watched less TVs ship out. Of course that shouldn’t be a problem for the fourth quarter of the year as people pick up TV sets as household holiday gifts.
