In a global marketplace, where companies are competing for new customers in unchartered markets, the mobile phone offers a valuable new marketing channel. Indeed, with more than five billion mobile subscribers across the globe today, mobility of communications and computing power is dramatically improving connectedness, making the world a smaller place and opening new market opportunities. As such, respondents say that mobile technologies are more likely to help business over the next five years than any other technology. ABI research, for example, expects the global market for mobile commerce to reach $163bn by 2015. Respondents across all sectors, in firms of all sizes, and in both the developed and emerging world consistently rated it as a game changer—in fact, more than 50% of respondents within each sector surveyed say their firms will invest heavily in mobile technologies over the next five years.
