Based on myth, Barthes initially established his own new semiotic theory (as opposed to Saussure's semiotic theory). He adopted a new style called "a kind of scientific humor" to analyze these "new myths" popular in French society and culture at that time. He pointed out that there were always two major factors in the mythical popular discourse at that time: one was ideological criticism under the banner of "popular culture" language; The second is the deconstruction of popular cultural language by the new symbol theory.
