There's almost no point in arguing this. Only on this board does social media not matter in 2016.
No one ever stated that. Let's look at some facts though:
NFL Facebook likes: 13,552,599
WWE Facebook likes: 31,037,477
NFL YouYube: 949,492 subscribers and 453,630,860 views
WWE YouTube: 10,729,518 subscribers and 8,465,994,576 views
NFL revenue in 2015: $12 billion
WWE revenue in 2015: $658 million
WWE dominates in social media metrics, but its revenue in comparison is laughable. Either the WWE has a large % of fake social media followers, or they are terrible at monetizing their social media following.
It's probably a mix of both. On TV for example, advertising rates for pro wrestling are exceptionally low.
