Comparing the baseball industry and p0rn is total wrong
Baseball is an industry with an audience mainly from North America. P0rn has a worldwide audience. Based on this the revenue generated is much bigger. As you know, p0rn isn't only about movies. This much bigger than this
It`s just an example, LG
An example to go into a bit more about the subject, only.. but I totally agree on adult industry`s not only about movies for sure. I also believe that there is a big, huge amount of "unrecorded" billions related with that, which has no relation with movies at all.
