what is the largest size tv you can buy in a store/
Worldâs Biggest TV is a Custom-Made, $1.6 Million 370-Inch Monster. A British company has created the world's biggest TV, leapfrogging the previous champ by almost 20 feet. The Zeus, from Titan Screens, measures a full 370 inches diagonally â and costs well over a million bucks. The number doesn't give an adequate estimation of the screen's size, though.
