There are a huge range of sports or activities professional boxing could learn from to develop interest and demand in the sport, but I really don’t see how this translates.
This YouTube boxing phenomenon is like someone has distilled all the marketing and bravado from Wrestling, with fewer steroids and a lot less athletic ability.
The financial outcome is only one measure of success, and I seriously doubt in 5 years time we will be tuning in for more of this. I don’t watch it now but as a kid WWF/WWE felt like it had more substance and longevity than this.
Good luck to them, they’ve made a decent wedge from putting on the events.
