Mobile commerce has been lately predicted to grow up to $31 billion by 2015 (Emarketer Inc.) in the USA. The term m-commerce is also one of the most popular words connected to retail. It concerns not only shopping online but apparently even the in-store shopping. Although it’s so powerful, don’t let yourself treat it as a separate notion. There’s also s-commerce, f-commerce, re-commerce and many more… And all of them eventually compound to simply e-commerce.
