Quick: Think of watching a YouTube video. What kind of screen pops into your head? Chances are you thought of your laptop, desktop, smartphone or tablet before you imagined flopping down in front of a YouTube video on your widescreen TV in the den.But that’s an attitude YouTube is desparate to change — and TV makers are eager to help them out. A number of sets launching at CES 2013 this week in Las Vegas — including sets from Bang & Olufsen, LG, Panasonic and Sony — offer the video service’s recently launched “send to TV” feature.This lets you pair an Android phone with a TV on the same Wi-Fi network, and cue up videos using the YouTube app as your remote. Sony and Samsung apps on some recently-sold TVs already work with the feature, as do TV apps on Xbox 360, PlayStation 3, Wii and Wii U consoles. Google TV not required. Controls in the iOS YouTube app are coming soon.
