The Letter U and the Numeral 2 is a 96-page magazine and 25-minute CD by Negativland detailing their conflict with the band U2, over Negativland's EP of the same name.[1][2] It was released in 1992 as a limited edition of 4000 copies. Two months after its release, SST Records blocked its distribution with a lawsuit claiming, among other things, copyright infringement based on reproductions of press releases sent to the press by SST; "in essence, suing the band for printing (their) threat to sue the band".[citation needed] SST's lawsuit is similar to the "Streisand effect".
