The Premier League and music publisher Bourne & Co first started the massive legal action against Google. The new parties joining the legal battle include the National Music Publishers' Association, which is the largest music publishing trade organization in the US, the Rugby Football League, the Finnish Football League Association and author Daniel Quinn.
"The clear and growing message to YouTube and Google is simple: their callous and opportunistic business model is contrary to right, contrary to law, and must and will be stopped," Premier League spokesman Dan Johnson said in a statement.
Google, however, will probably contend to be complying with the law by immediately taking down any clips found to be violating copyrights after receiving notification. The same argument it plans to make when defending itself against media giant Viacom's $1 billion copyright lawsuit.
