If you can write a little something about history behind the transition between real wrestling and the "show" of pro wrestling that would be pretty interresting...
well if your doing the history of Puro you have to start with Rikidozan cause he's really the first one. Then you move on to the Baba/Inoki era and them both starting their own promotions. And then just talk about now with the huge number of promotions and some of the big changes of the last 5 or so years like the Noah exodus and the Zero-One breakoff, and the new focus of MMA in NJ Pro.
As far as Lucha.....I dont know all that much about it but you have to talk about El Santo thats just a given. You can also talk about some of the Lucha Families like the Villanos and the Guerreros. If you want you can also talk about how Lucha had influenced Jr. Heavyweight Puro through guys like Tiger Mask, Ultimo and Liger and some of the crossover stars like Gran Hamada and Dr. Wagner
