Samsung outpaced all brands in North American LCD TV market share during the fourth quarter of 2007, knocking Vizio, the leader for the prior two quarters back to third place, according to TWICE Magazine.

TWICE quotes a report from the market research firm iSuppli which said that Samsungs fourth-quarter unit-shipment market share rose to 14.2 percent, up from 12.8 percent in the third quarter. The South Korean company had been in second place in the third quarter.

Sony, which took the second spot during the quarter, increased its market share to 12.5 percent, up from 10.8 percent in the third. Sony had been in fourth place during the third quarter.

U.S.-based Vizio, meanwhile, saw its market share decline in the fourth quarter to 12.4 percent, down from 13 percent in the third quarter.

iSuppli said Vizio had risen to the top spot due to a combination of low pricing and high-visibility sales channels. However, Samsung and Sony struck back with their own low pricing in the fourth quarter.
