Berg Insight predicted that the global number of cellular machine-to-machine (M2M) subscribers would reach 1 billion in 2022 after rising by a compound annual growth rate (CAGR) of 22.9 per cent over the next five years. In 2015, the number is expected to have increased by 23 per cent to reach 265.2 million at the end of the year. East Asia was the largest regional market this year with 90.4 million M2M subscribers, followed by Western Europe and North America with 59 million and 52.5 million respectively. The research company noted that as the cellular M2M market continues to grow, it is also starting to generate substantial revenues for leading telecom operator groups. Verizon and Vodafone reported quarterly M2M/IoT revenues in the range of €150 million - €200 million each in the first half of 2015 and could be on track to reach €1 billion on an annual basis within a few years' time.
