You plug Google's new $35 Chromecast dongle into the back of your TV set to wirelessly stream Internet video on a larger screen. "For Bigger Fun," this minute-long commercial by 72andSunny, shows all kinds of people doing just that. They watch mainly Hollywood fare (Charlie Chaplin, Austin Powers, etc.) or candid footage from their own lives. In a way, this is the YouTube generation coming full circle, as we can now broadcast ourselves onto our living-room screens and enjoy a stripped-down version of old-school TV stardom. The spot works hard to portray Chromecast as an enjoyable shared experience, though watching people watch TV isn't that exciting. The music, "Zorba the Greek," sets my teeth on edge. It reminds me of the bloody bouzouki that drones on and on and on and on in Monty Python's "Cheese Shop" sketch. Now there's some video worth streaming! Bottom line: Dongle's a funny word. Kind of.
