#4 SmackDown has always been a show that has a PG rating
The wrestling world is changing, there was a time when Monday Night RAW was the main wrestling show that was aimed at much edgier wrestling fans. Over the years, WWE has developed its show so that it's aimed at a much younger demographic, which is why AEW has the TV-14 rating rather than the PG rating that WWE is currently enjoying.
Despite many members of the WWE Universe often calling the company out for the fact that it's toned down much of its content. According to WWE's official website, SmackDown has always had a PG rating throughout the past two decades.
"Other WWE programming gradually transitioned to TV-PG content and storylines, officially being recognized as TV-PG by WWE’s television network partners’ standards and practices departments in July 2008."
There was a time when First Blood matches were a regular gimmick, but the company has since managed to sugarcoat a lot of its content and tried its hardest to ensure that there is no blood so that they remain in line with the rules for their TV-PG content.
