Other companies, such as Michinoku Pro Wrestling and Dragon Gate, wrestle in a style similar to Mexican companies like AAA and CMLL. This is known as "Lucharesu". Developed culture Professional wrestling has developed its own unique culture. Those involved in producing professional wrestling have developed a kind of global fraternity, with familial bonds, shared language and passed-down traditions. New performers are expected to "pay their dues" for a few years by working in lower-profile promotions and working as ring crew before working their way upward. The permanent rosters of most promotions develop a backstage pecking order, with veterans mediating conflicts and mentoring younger wrestlers. For many decades (and still to a lesser extent today) performers were expected to keep the illusions of wrestling's legitimacy alive even while not performing, essentially acting in character any time they were in public. Some veterans speak of a "sickness" among wrestling performers, an inexplicable pull to remain active in the wrestling world despite the devastating effects the job can have on one's life and health. Fans of professional wrestling have their own subculture, comparable to those of science fiction, video games, or comic books. Those who are interested in the backstage occurrences, future storylines and reasonings behind company decisions read newsletters written by journalists with inside ties to the wrestling industry. These "rags" or "dirt sheets" have expanded into the Internet, where their information can be dispensed on an up-to-the-minute basis. Some have expanded into radio shows. Some fans enjoy a pastime of collecting recordings of wrestling shows from specific companies, of certain wrestlers, or of specific genres. The internet has given fans exposure to worldwide variations of wrestling they are unable to otherwise see. Since the 1990s, many companies have been founded which deal primarily in wrestling footage. When the WWE purchased both WCW and ECW in 2001, they also obtained the entire past video libraries of both productions and have released many past matches online and on home video. Like some other sports, fantasy leagues have developed around professional wrestling. Some take this concept further by creating E-feds (electronic federations), where a user can create their own fictional wrestling character, and role-playing storylines with other users, leading to scheduled "shows" where match results are determined by the organizers, usually based on a combination of the characters' statistics and the players' roleplaying aptitude, sometimes with audience voting.
