Oh, how the times they are a-changin'. Merely months after Vizio ousted Samsung as the LCD TV king in Q2, Sammy is back on top of overall flat-panel TV sales here in North America. Thanks primarily to a staggering 37-percent quarter-to-quarter growth rate (compared to Vizio's 12-percent), Samsung now has an 11.8-percent unit share compared to Vizio's 10.2-percent. Strictly looking at LCD TVs, Vizio still isn't holding the gold; rather, Sharp rocketed ahead to the top spot in that category and left the previous leader clinging to second. It should be noted that Vizio's sales are far from stagnant -- the firm has experienced a 334-percent increase year-to-year in LCD TV growth compared to Sharp's 88-percent. Still, we wouldn't count on the current leaderboard staying this way for long, as Black Friday (and the holiday season in general) has a tendency to shake things up.
