The bbc.co.uk website was launched in December 1997, three years after the first BBC web pages were developed.
Ralph Rivera, director of Future Media explained in a blog: "Innovation is at the heart of the BBC and has been since its inception.
"From when the BBC opened its first radio station in 1922 and launched the world's first regular television service in 1936 few could have imagined just what impact broadcasting would make on our everyday lives."
He added: "Just as radio and TV did before it, the digital revolution has fundamentally changed how our audiences access news, information and programmes.
"As one of the first major organisations in the UK to embrace the web the birth of the BBC's websites 15 years ago is an important milestone in that evolution."
The broadcaster has published a series of videos and interviews to mark the landmark anniversary, one of which you can watch below:
