British girl groups are musical ensembles consisting of female singers, often known for their catchy songs and synchronized dance routines. They gained popularity in the 1960s with groups like The Supremes and later with The Spice Girls in the 1990s, who became global icons. These groups typically focus on pop music and have a significant influence on fashion and youth culture. Over the years, British girl groups have evolved, with newer acts like Little Mix and Girls Aloud continuing the tradition. They often address themes of empowerment and friendship in their lyrics, appealing to a wide audience and contributing to the music industry.
