In the fall of 2010 the Transportation Security Administration began implenting new body scanners at airports in an effort to comabt potential threats. Some objected to the invasiveness of a scan that showed a given air passenger basically naked on a computer screen. If they chose not to be scanned, they would be subjected to a lengthy and thorough "enhanced" pat-down. One objector to this new policy launched an effort called "National Opt-Out Day." Under this effort, air travelers on Wednesday 11/24/2010 were asked to "opt-out" of the scan and submit to the pat down.
In response, Appealing Industrues launched "Opt-In Day" for the same day, encouraging people to submit to the scans. Whern the dust settled, many more Americans opted in than opted out.
