(CNN)The inventor of the world wide web has warned that it is "not working for women and girls" as he stressed the importance of tackling gender equality.
Tim Berners-Lee wrote in an open letter to commemorate the 31st anniversary of the revolutionary technology that women of color and those from LGBTQ+ and other marginalized communities still face acute discrimination.
"This should concern us all. Women's rights are human rights and are fundamental to a healthy society, from reducing poverty and disease to improving education and economic growth," he wrote in his letter.
"And so it's up to all of us to make the web work for everyone." Berners-Lee said the call to action was "compelling and urgent."
He urged those who shape technology -- from CEOs to academics, engineers and public officials -- to tackle online harms against women as a priority.
To date, he said, action had "been too slow and too small."
He called for new legal protections to hold perpetrators of online gender-based violence to account, and said governments and companies should publish data on the experiences of women online -- who often suffer "relentless" threats and sexual harassment.
He said that 2020 "must be the year"
