rtners 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." Men are marrying later, if at all, which impacts male bonding. According to the 2010 US Census, the average age of a man's first marriage is 28, up from 23 in 1960; men with more education are waiting until their 30s before getting married. Celebrity A number of celebrity relationships have been popularly characterised as "bromances". 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, a s 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 television and in nightclubs. They had an immeasurable effect on millions of baby boomers and future comedians, (including George Clooney, whose aunt Rosemary Clooney was a guest on their show). Ben Affleck and Matt Damon were described as "perhaps the pioneering bromance in showbiz history", which led to an off-Broadway play called Matt and Ben. The relationship between Zachary Quinto and Chris Pine, stars of the 2009 Star Trek film, has been described similarly, in common with their on-screen characters' relationship. The close friendship between George Clooney and Brad Pitt was once suggested to be "George's longest-last ing affair" and Clooney's bromantic tendencies served as the basis for an episode of the animated series American Dad! entitled "Tears of a Clooney", in which lead character Stan Smith becomes bromantically involved with Clooney as part of an elaborate revenge plot. Athletes Professional footballers Eric Dier and Dele Alli, who play together for both Tottenham Hotspur and the English national team, have a close relationship that has been described as a bromance. During the 2016 Olympic 100m finals, the friendship between Jamaican Usain Bolt and Canadian Andre De Grasse emerged, characterized and celebrated on social media as a bromance. Bodybuilders Arnold Schwarzenegger and Franco Columbu, had a close relationship described by themselves as bromance, since 1965. Arnold and Franco were inseparable friends and training partners since then. They began a bricklaying and patio business called Eu
