"The Stop Online Piracy Act (SOPA), also
known as H.R.3261, was introduced in the
United States House of Representatives on
October 26, 2011 by Representative Lamar
Smith [R-TX] and a bipartisan group of 12
initial co-sponsors. The aim of the bill is
to help U.S. law enforcement and copyright
holders fight online transmission of
restricted intellectual property."
