Eyes On ratings were
initially released for only 10,000 outdoor units in Chicago. Next month, the new system will be rolled out in more than 200 markets covering ratings for about 400,000 units. Chris Gagen,
Posterscope USA's managing director, claims that OOH "is becoming the first medium that will give audience data based on the number of people seeing an ad, versus the number of people exposed to
it."
Prior to Eyes On, the outdoor industry sold ad inventory with the TAB's Daily Effective Circulation figures, which were simply raw counts of passersby. Buyers often discounted the
measure to about 20% to 30% of the DEC value.
