privilege and subordination imbued in this type of relationship, with implications for other types as well." This is distinct from the connotations of romantic friendship, a term of 20th century historical scholarship that retrospectively described close homosocial relationships, which had become less common after potential physical intimacy between non-sexual partners came to be regarded with anxiety in the second half of the 19th century. On the one hand, social interest in the theme has been seen as driving the film industry, which has then fed back to society at large, exploring peoples' mindsets and addressing acceptance of "other types of relationships" between people. On the other hand, some have seen the emphasis on platonic love as a rejection of homoeroticism, or as a deliberate confounding of homosocial and homoerotic relationships. Bromance has also been seen as a reflection of greater "discursive expressivity". The experiences of friendship and masculinity, perhaps due to more open parenting styles from the 1970s, reflect a trend toward more openness emotionally, with increased expressivity. According to sociologist Peter Nardi, "men are less afraid of being perceived as gay. It has become more acceptable for them to show some emotion."

Although bromance is a new term, this treatment of celebrity relationships is not new: The composer Franz Schubert had a very close friendship with poet Franz von Schober, whose texts Schubert set to music. They were nicknamed "Schobert" in early 19th century Vienna. Film celebrities Dean Martin and Jerry Lewis as the 1946-1956 ‘rock star’ comedy team Martin and Lewis set a new standard for a complex, multifaceted enactment of a ‘special’ male friendship." Coming post-war, "the comedy of Martin and Lewis teased with a sly alternative to the model of heterosexual affirmation traditionally peddled by Hollywood, as their intense and unstable relationship showcased a panoply of emotional and erotic intensities between men. The cultural resonance of Martin and Lewis's comedy derived from the way it set in motion a more complex ‘queering of gender.’" They starred in 16 films together as an inseparable unit, as well as on early live
