There it stood: the 65-inch Samsung LED. It was sleek, with a bezel so thin it practically disappeared into the dark gray wall behind it. Marcus grabbed the remote and flicked on a demo of a deep-sea documentary. The blacks were so inky that the bioluminescent jellyfish seemed to float in the air between Leo and the screen. "This is the one," Leo whispered.

Leo stood in the middle of the Best Buy showroom, paralyzed by the wall of glowing glass. He had been saving for six months, and today was the day he would finally upgrade his living room. His old set was a relic that hummed when it got too hot; he wanted something that felt like a window into another world.

A blue-shirted employee named Marcus approached with a knowing smile. He didn’t try to upsell Leo on the massive 85-inch screens that looked like billboards. Instead, he walked him straight to the sweet spot of the home theater aisle.

After a quick trip to the checkout counter and a slightly awkward struggle to fit the box into his sedan, Leo finally got it home. He spent the afternoon carefully mounting it, hiding the cables, and dimming the lights.
