RIAA stands for Recording Industry Association of America. They are a conglomerate formed of all the big recording lables in the United States (like United Music Group, which we talked about here)
They're one of the organizations behind the Stop Online Piracy Act (SOPA) which is making its way through congress. As we've mentioned, the bill will impose really restricting rules on the internet and will allow them to majorly change the internet. SOPA is opposed by pretty much all major tech companies.
So it's just a little bit hypocritical that the RIAA has been found pirating over 60 episodes of the TV show Dexter! This was discovered thanks to the website youhavedownloaded.com which tells you every publicly available torrent that your IP has downloaded.
If we apply the same math that they have applied when prosecuting downloaders, then every episode they pirated is worth $150,000 which means that they have pirated over $9 million worth of Dexter.
