Old Spice?

So I watch YouTube obviously like a lot of people do. I was just watching a dorm tour from a girl that moved in a while ago and I've always noticed that they have regular deodorant, you know like dove, women's deoderant. But I've also noticed that the majority of them have Old Spice too? And it's not just college people, it's just general women on youtube, that I've seen that with. What is up with that?
