Tropicália's controversy can be traced to the uncertain and unfriendly relationship the members of the movement had with the mass media. The movement's emphasis on art clashed with the media's need for mass appeal and marketability. Tropicália additionally had an image of sensuality and flamboyance. This was a protest to the reinstated oppression of Brazil's military rule in the 1960s, and an additional cause for media pushback. In 1968, Tropicália events at clubs, music festivals, and television shows attracted media attention and aroused tension between Caetano Veloso and Gilberto Gil and their critics. This widespread attention attracted military attention and suspicion, who feared Tropicália's influence of protest in the cultural realm.
