C'est la question que pose un article en anglais ici et qui fait débat sur plusieurs autres sites.

Il est plus question de télé que de littérature...

The current generation of boys will not have this inspiration from science fiction, at least from science fiction on television and in movies. That’s because there is an undeclared war on real science fiction on TV and in movies. The former Sci-Fi channel, now “Syfy”, is a good example of what has been happening to science fiction on television. In 1998 Bonnie Hammer took over the Sci-Fi channel and declared that “more female viewers were needed”. Over the next several years, the Sci-Fi channel became increasingly feminized losing many of its traditional male viewers in an attempt to go after women viewers. This included making the logos “warmer and more human” because the logos before were “too male and too dark”. The biggest change was in the feminization of the programming shown on the Sci-Fi channel. The re-imagined re-delusioned Battlestar Galactica is a good example. (Many of you might not be aware but there was an original Battlestar Galactica series shown in the late 70s.) While the original series had its problems, it was more standard science fiction with men doing and accomplishing things. The new series instead had lots of relationship drama, men whining, and men generally unable to find their way out of a wet paper bag. The new Battlestar Galactica was so feminized that one of the main characters from the original series, Starbuck, (who was a man) was turned into a woman. When Bonnie Hammer first heard about this, she clenched her fists in the air and yelled, “Yes!”. There’s so much more that can be said about this, but rather than write pages and pages more, everyone should read what Dirk Benedict, the original and only Starbuck had to say about it in a piece called, Lt. Starbuck…Lost in Castration. (Run, do not walk to that webpage. It’s that good.)"
