Background: A boy band (or boyband) is loosely defined as a vocal group consisting of young male singers, usually in their teenage years or in their twenties at the time of formation, singing love songs marketed towards young women. Being vocal groups, most boy band members do not play musical instruments, either in recording sessions or on stage, making the term something of a misnomer. However, exceptions do exist. Many boy bands dance as well as sing, usually giving highly choreographed performances.
Context: Other antecedents (apart from those already mentioned) exist throughout the history of pop music. The genre has been copied into languages and cultures other than the Anglo-American. The Puerto Rican boy band Menudo, appealing to young Latina audiences, was founded in 1977. Menudo had a convention unique among boy bands: when a member turned 16, became too tall, or their voice changed, they were replaced. The members of Menudo were generally aged 12-16.  The Bay City Rollers were a Scottish pop band who were most popular in the mid-1970s. The British Hit Singles & Albums noted that they were "tartan teen sensations from Edinburgh", and were "the first of many acts heralded as the 'Biggest Group since The Beatles' and one of the most screamed-at teeny-bopper acts of the 1970s". For a fairly brief but fervent period (nicknamed "Rollermania"), they were worldwide teen idols. The group were one of the first bands, like The Monkees before them, to take the formula shown by The Beatles and apply it to a teen market. The group achieved the same amount of success but for a limited period of time. At the peak of their popularity in the UK, comparisons were being made to The Beatles. Also by this time, Bay City Roller fans had a completely distinctive style of dress, the main elements of which were ankle-length tartan trousers and tartan scarves, the group using the benefit of merchandise and promotion.  In the US, the Cleveland-based power pop group Raspberries was generally interpreted as a "teen act", although all the band members played their own music. Vocalist Eric Carmen later commented, "It was not hip for people to like us, because their little sister liked us."  Boston group New Edition was formed in 1978 and reached their height of popularity in the 1980s, meaning they are often credited for starting the boy-band trend, even though the term "boy band" did not exist until the 1990s. Maurice Starr was influenced by New Edition and popularized it with his protege New Kids on the Block, the first commercially successful modern boy band, who formed in 1984 and found international success in 1988. Starr's idea was to take the traditional template from the R&B genre (in this case his teenage band New Edition) and apply it to a pop genre.  Bros (abbreviation of the word "brothers") were a British boy band active in the late 1980s and early 1990s, consisting of twin brothers Matt and Luke Goss along with Craig Logan. Formed in 1986, they scored multiple top 10 hits between 1987 and 1989 and in 1988 became the first modern era-style boy band to have a multiple platinum-selling album in Britain, with Push, still one of the most successful boy-band albums in the UK. Other big boy bands in Britain during the late 1980s were Big Fun and Brother Beyond.
