Through the use of the masks and ring characters EMLL helped create the sacred position of the mask in Lucha libre, making it the ultimate status symbol for luchadors.[1][2] In the early days of EMLL most of the top names were Americans, but with time EMLL introduced several Mexican natives that became so popular that they began to main event most of the EMLL shows. In order to expand their business EMLL began working with a number of local wrestling promoters across Mexico, allowing them to use the EMLL name and some of their contracted wrestlers while also gaining access to local wrestlers in return. Each booking office was independent of each other but the main office in Mexico City had the final say if there were disputes over who would be able to book certain wrestlers.[1][2]
