#3 The numbers do not lie
All you have to do is visit the YouTube page if you don't believe me. The video with Alexa Bliss announcing the historic women's tag team championships has a lot fewer views than the video where she has a stagehand catch her absolutely unaware.
The fact of the matter is that WWE's audience comprises of hot-blooded males and they may want to consume entertainment of this very nature. Drama and gossip have been the foundation for many of WWE's feuds and this is what separates sports entertainment from actual sports. Alexa Bliss is gorgeous and people want to see her beyond the ring.
Does this fit into what is being called The Women's Revolution? In my opinion, it does because you're serving a palette of entertainment to cater to every palate.
And WWE fans are used to this kind of entertainment, especially those who've been watching for a while.
