Pop music originated around 50 years ago and began gaining mainstream popularity with Elvis Presley in the 1950s. Pop music is characterized by short, simple songs that utilize technology to produce variations on familiar themes and are often aimed at a youth audience. Key figures like Michael Jackson and The Beatles helped establish pop music as a commercial genre that absorbed influences from other popular styles. Pop artists frequently rose to fame at a young age and produced albums featuring danceable songs that sometimes had "cheesy" or soppy lyrics. Major pop albums from 1970 to the present spanned artists from Michael Jackson and Madonna to Justin Bieber, Lady Gaga, and Rihanna.
