So let's think about company oneliners. I like the exercise, as it goes to the heart of a company's strategy.
As an aside, my old screenwriting flatmate in san francisco was an expert at pitching hollywood movies. So I quizzed him on it. I asked him "How do you describe E.T.", imagining he'd say something about the yearning for home, being lost, etc... He thought for a second and said "Lassie from outer space; alien gets found by kids, they hide him from parents, kids get in trouble, saves the day; lassie". Funny huh?
So... company oneliners.
Facebook..."A better television, cause it's my friends on it." After all, its replacing time people would spend in front of the tube, no? I'd say it's entertainment + communication.
Let's do Android... Would this be "iPhone meets Linux"? You know, cool experience meets open source. Bah. Explaining it takes the fun out of it.
One more, one more. Twitter. Why not. Everyone talked about it (on it) at some time. So this could be "SMS on steroids meets social networking?" Hmmmm. A bit boring maybe. Think more on this one...
