Whether you are a photographer or an aspiring model, Instagram, the San Francisco-based mobile photo sharing service has become a place to share photos and then be discovered. It was recently named App of the year by Apple and it has seen a serious growth spurt. I have always though of television as an analog for Instagram. Levi’s, the denim people are using the service to find their next new model. Simple – share photo on Instagram and tag it, #IAMLEVIS.
