October 7th 1946 was the start of something big - it was the first broadcast of a programme designed to celebrate, entertain and inform women.
Woman's Hour now attracts an audience of some 2.7 million people across the week - and over 40% of our listeners are men.
We'll be celebrating the anniversary with special entertainment on Saturday 07 October at 16.00 on Radio 4 and there are discussions around a wide range of people, events and significant issues during the weeks leading up to the actual day.
