 In March 2014, Cessna ceased operations as a company and instead became a brand of Textron Aviation.During the 1950s and 1960s, Cessna's marketing department followed the lead of Detroit automakers and came up with many unique marketing terms in an effort to differentiate its product line from their competitions'.Other manufacturers and the aviation press widely ridiculed and spoofed many of the marketing terms, but Cessna built and sold more aircraft than any other manufacturer during the boom years of the 1960s and 1970s.
