Mobile computing allows users to access the internet on portable devices like smartphones and tablets. Smartphone adoption has grown significantly since their introduction. The top operating systems are Android and iOS. Social networks like Facebook, Twitter, and LinkedIn saw rapid growth in mobile access in 2010. This allows marketers new opportunities through mobile apps, text messaging, and mobile ads. Branded social networks created by companies and location-based networks like Foursquare are two key ways marketers can leverage mobile. Location-based networks allow deals, discounts and games to engage users and drive awareness and sales. The future of mobile marketing may involve more personalized, location-aware ads and offers tailored to individual behaviors.
