8. Spice Girls
For six years, the Spice Girls danced around in skimpy clothes singing catchy songs and causing chaos around the UK but the phenomenon of Girl Power was something none of them expected. The Spice Girls preached this notion in everything they did, creating a huge wave of feminism that had a huge impact on women in Britain of all ages. Coupled with peace signs and raucous laughter, it was Ginger Spice/Geri Halliwell who really led the movement and in recent years the star has even said that it was her early brush with feminism that led her to realise just how important standing up for women is. However, a recent blunder last year saw Geri name the recently deceased Margaret Thatcher as the '1st Lady of Girl Power.' Awkwardness aside, the phenomenon really worked as the key to the band's success. However, the concept of Girl Power was also met with some criticism. Many critics saw the phenomenon simply as a marketing tool and as a way of making the Spice Girls somewhat unique while still maintaining their popularity with the masses. In another controversy, a journalist suggested that Spice Girls were the wrong people to be portraying the phenomenon, claiming that the philosophy would make more sense if there was a fat Spice Girl or a spotty Spice Girl. In spite of this, the concept grew and grew during the Girls' popularity and has marked a place in history for this brand of feminism, making the Spice Girls a band with something important to say.
