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.

The earliest forerunner of boy band music began in the late 19th century as a cappella barbershop quartets. They were usually a group of males and sang in four-part harmonies. Barbershop quartets were popular into the earlier part of the 20th century. A revival of the male vocal group took place in the late 1940s and 1950s with the use of doo-wop music. Doo-wop bands sang about topics such as love and other themes used in pop music. The earliest traces of boy bands were in the mid-1950s although the term boy band was not used. African American vocal group The Ink Spots was one of the first of what would now be called boy bands. The term boy band was not established until the late 1980s as before that they were called male vocal groups or "hep harmony singing groups".  Although generally described as a rock band, the highest-selling band in history The Beatles are considered by a number or journalists "the first" or "the original" boyband, "before anyone had thought of the term."  The Liverpool quartet known as The Beatles were not only the quintessential rock band, but many considered John Lennon, Paul McCartney, George Harrison and Ringo Star to be the original boy band -- especially in the early 1960s when young girls would scream at the top of their lungs and pass out upon first sight of the "Fab Four.  The Beatles inspired the decision to produce the 1966 television series The Monkees, which spawned the music group of the same name, formed by the four starring actors. The rock and pop band started a career in music after their songs from the TV series released as records resulted successful. Answer this question using a quote from the following article:
