Today, blading is a lot less popular than in the past, due to the prevalence and heightened awareness of AIDS and hepatitis. In the 1980s, the willingness to blade was seen as an advantage of new wrestlers. From July 2008 onward, due to its TV-PG rating, WWE has not allowed wrestlers to blade themselves. In most cases, any blood coming from the wrestlers is unintentional. To maintain their TV-PG rating, when a wrestler bleeds on live television, WWE tends to attempt to stop the bleeding mid-match or use different camera angles to avoid showing excessive blood. During repeats of said footage, WWE television programs often shift to black-and-white.
