When were women first allowed to watch the olympics?

Answer 1

According to Topendsports: Even in the early years of the modern Olympics, women were not well represented (consequently a rival Women's Olympics was held). Women participated for the first time at the 1900 Paris Games with the inclusion of women's events in lawn tennis and Golf. Women's athletics and gymnastics debuted at the 1928 Olympics.

But in wikipedia it is mentioned that, The 2012 Olympic Games in London were the first Olympics where every participating country included female athletes. They were also the first Olympics in which women competed in all sports in the program.

Another interesting fact that i found in the blog of PureVPN about Winter Olympics Facts i was reading earlier, The 2014 winter Olympics were the first time women were allowed to participate in Ski Jumping.
