* – Due to a change in the type of call used behind Facebook’s AJAX interface, Nielsen NetView data for Facebook duration was underreported for June and July, impacting overall web use figures for those months. Therefore, Time Spent and Page Views per Person for August should not be trended against July 2011 data.
