NSA released on 23 July 2013 "The History of Traffic Analysis:
World War I-Vietnam."

http://www.nsa.gov/about/_files/cryptologic_heritage/publications/misc/traffic_analysis.pdf

It notes the formation of T/A (Traffic Analysis) and C/A (Cryptanalysis)
as the two elements of code-breaking, using the mail analogy of T/A
for the envelope, C/A for the contents.

As noted elsewhere T/A is now publicized as "metadata."
