Telecom NZ reports an 83 percent growth in data use on its mobile network in the past year. It says increasing smartphone ownership and video streaming applications are behind the surge. The company reports the average amount of data per customer on the mobile network was 396 MB in September 2013 compared with 385 MB in August and 253 MB in September 2012. Telecom NZ also specifically mentions the America's Cup yacht races as responsible for the kickstarting the popularity of video on mobile phones. Recently I spoke to a senior Telecom executive who said the race series in San Francisco was a turning point for streaming.
