In a surprise move today, Representative Eric Cantor(R-VA) announced that he will stop all action on SOPA, effectively killing the bill. This move was most likely due to several things. One of those things is that SOPA and PIPA met huge online protest against the bills. Another reason would be that the White House threatened to veto the bill if it had passed. .
PIPA, the Senate Version is still in play, however.
