Vizio has been one of the top selling LCD brands the last few years. It seems Vizio and Samsung are constantly leap-frogging one another as the top dog. Well, Vizio’s back on top. The company just posted an iSuppli report indicating the brand reached a 18% shipping marketshare for all of 2010 in North America and a 21% level for just the US. Both Vizio and Samsung saw increased shipments while Sony’s numbers fell. It was Vizio that saw the largest increase therefore claiming the title back from Samsung. It’s good to be king.
