The bump chart shows the evolution of TV series which quote the NSA from 1968 to nowadays. The production of TV series concerned with NSA started to increase massively in 2002 with 22 episodes (6 episodes in 2001). Such growth coincides with 9/11 and subsequent increase of security measures.
Some peaks emerge: the first one in 2003 with 28 episodes, then in 2005, 2007, 2011 and the last one in 2014 with 89 episodes.
The greatest part of these episodes is classified as drama but there is an interesting genre turnover between 2001 and 2011.
