Email and search engine usage, two of the most common digital activities, have also reached saturation among internet users. For the vast majority of internet users, email and search are basic functions necessary to efficiently use the web—and navigate daily life—unlike other digital activities such as social networking, video viewing or gaming.
eMarketer expects there to be 216.6 million US email users this year, representing 89% of total internet users. Two out of three people in the US will be email users in 2013. Growth will be slightly under 3% between 2013 and 2014 and will slow to 2% thereafter. Read the rest at eMarketer.
