Meet the 10 most influential women on Twitter

So, who are the biggest female voices on the Twittersphere today?

When Twitter was first launched in March 2006, no one could have anticipated how it would evolve. Ten years on and women across the globe are using the platform to promote their voices. These are some of the most influential on social media today.

Katy Perry/ @katyperry (90 million followers) Katy Perry made her Twitter debut in 2009 and has held her title of the most followed person in the world since 2013. The singer surpassed 80 million followers in January - over 10 million more than US president Barack Obama. Offering a backstage pass to her superstar life, she also shares inspirational quotes and advice. In one of her most shared tweets of all time she highlighted the irony of women pitting themselves against each other, amid the bad blood between herself and Taylor Swift.

Ellen DeGeneres/ @TheEllenShow (60.6 million followers)

Talk show host Ellen DeGeneres holds the record for the most retweets of all time with her 2014 Oscars selfie featuring Brad Pitt, Julia Roberts and Jennifer Lawrence. Regularly speaking to the world's biggest celebrities, she's funny, sharp, straight talking and a huge name in feminism.

Lady Gaga /@ladygaga (61 million followers) Five years ago Forbes crowned Gaga the most powerful celebrity in the world, and with almost 60 million Twitter followers to date she's not about to let that slip. Earlier this year the singer-songwriter won a Golden Globe for her first foray into acting and Editor Of The Year for her work on V Magazine, proving she's still relevant and deserving of her ever-expanding fan base. Her song 'Til It Happens To You promotes awareness of sexual assault and support for survivors, giving a voice to women around the world.
