The ReThink911 campaign is back for the 13th Anniversary of 9/11 with this two-sided digital billboard right in the heart of the Times Square district, each side measuring 45 ft x 45 ft. Located at the northeast corner of 42nd St. and 8th Ave. and pointing both west and south for all passersby to see, this billboard gives viewers a high-impact introduction to the destruction of World Trade Center Building 7, a 47-story skyscraper that collapsed symmetrically into its own footprint at free-fall acceleration at 5:20pm on 9/11. The ad will run for 15 seconds out of every two minutes for 20 hours a day from September 8 to October 5, being seen by over 100,000 people each day, and about 3 million people throughout the month.
