Note (*1): The survey was administered by the Net Rating Office at Video Research Interactive Inc., and recorded the level of Internet usage of males and female subjects of four years or older using their home PCs.
Note (*2): The survey covered the above subjects and the 4,050 respondents to a November 2007 WebPAC survey (targeting survey subjects) who said that they had used the Internet during the month of September 2008. The number of minutes each subject spent online during the month was calculated to derive a bell curve for Internet usage. The leftmost third were classified as light users, the middle third average users, and the rightmost third heavy users.
Light users spent less than 3 hours and 12 minutes online, average users between 3 hours and 12 minutes and less than 16 hours and 13 minutes, and heavy users 900 minutes or more.
In addition, magazine readers were defined using the results of the WebPAC survey as persons who had read at least one of the 364 magazines in the survey (or for readers by genre, a magazine in that genre) during the last three months.
