This document discusses the rise of mobile commerce due to the mobile revolution. It notes that mobile usage has grown dramatically in just a few years, with over 2 hours per day spent on mobile devices. This level of mobile engagement provides opportunities for e-commerce, including making purchases, getting promotions, sharing content socially, and using location-based services. However, mobile e-commerce experiences need to be optimized for the mobile context with easy payment flows, rich interactions, and consideration of how users are constantly being tracked on their devices. Developers can explore different models for monetizing mobile apps, such as selling the app, in-app purchases, sponsorships or advertising. While competition is intense, the growing mobile market provides many opportunities.
