The RIAA refused to name the companies that have received letters. "We demand that you immediately cease-and-desist from enabling and inducing the infringement of RIAA member sound recordings. If you wish to discuss pre-litigation resolution of these claims against you, please contact us immediately." the RIAA states in a copy of a letter that News.com managed to obtain.
The letter also goes on to say that the Grokster decision applies equally to this certain company and certain individuals at the company. BearShare, WinMX and LimeWire were identified in a Wall Street Journal story as recipients of the letters but none have commented. So now the entertainment industry after having some success from the Supreme Court (although not exactly what it had hoped for) appears to be intending to see just how much it can squeeze from the Grokster ruling.
Many experts feared that after the ruling, entertainment companies would abuse the ruling.
