A new browser study performed by University of Hamburg researchers found a shift in how we interact with the Web - moving from static hypertext information to dynamic interactive services. The report examining navigation by tracking page reloads, web site viewing patterns and screen size dimensions. According to the report:
"With the increase in new windows and use of AJAX, the back button has dropped from over 35% to less than 15% of all page transitions. Overall the trend reflects an increase in interactivity and form submission, with a corresponding 50% drop in the use of the back button for web navigation."
