In the aftermath of the September 11 attacksthe NSA created new IT systems to deal with the flood of information from new technologies like the Internet and cellphones.
ThinThread contained advanced data mining capabilities. It also had a "privacy mechanism"; surveillance was stored encrypted; decryption required a warrant. The research done under this program may have contributed to the technology used in later systems. Some NSA whistleblowers complained internally about major problems surrounding Trailblazer.

Polls conducted in June found divided results among Americans regarding NSA's secret data collection.
