ELISE STRACHAN, MY CUPCAKE ADDICTION: I can only make so many cakes in a day. But I can make that cake and I can put it out on YouTube and its reach is endless.
STELTER: Elise Strachan is a YouTube creator. Over the past four years, her baking videos have earned her over 2 million subscribers. And like the rest of YouTube, half of her views come from mobile screens.
STRACHAN: You`re in these people`s bedrooms. You know, you`re on the train with them. You`re at school when they`re not probably (INAUDIBLE), they`re looking at their phones. But you`re going everywhere with them.
STELTER: That kind of intimacy with viewers is something new from media makers. And it could pay off big time. Mobile revenue for YouTube is up 100 percent year over year. And global business head Robert Kinzel (ph) doesn`t see it going down.
