Online Publishers Association - Internet Activity Index

(OPA)
The Internet Activity Index (IAI) provides a new way of looking at consumer engagement online, dividing Internet usage into four distinct activities: content, communications, commerce and search. The IAI is derived from a categorization of Web properties accounting for more than 90%, on average, of active Web users and approximately 55% of total usage time (excludes .gov and .edu Web sites, as well as pornographic domains).
