“As smartphones and data plans become more affordable than ever, they are positioned to become the default device for internet access,” said Corey McNair, author of a new eMarketer report, “US Digital Users: The eMarketer Forecast for 2017,” (available only to eMarketer PRO subscribers). “The number of these mobile-only users will see steady growth over the next few years, reaching 52.3 million in 2021.”
The number of mobile-only users is on the rise, totaling 40.7 million this year, up from 36.6 million in 2016.
Over three-quarters of US internet users will access the internet via both a mobile device and PC in 2017, and there will be roughly 9 million new dual-device users throughout the forecast period.
