The Politics and Play of ®TMark: “®TMark is an online centre that organizes and directs funding for the ‘information alteration’ of corporate products (otherwise known as “sabotage”). In 1993, ®TMark was involved in its first high-profile act of sabotage when it channelled $US 8000 to the Barbie Liberation Organization (BLO), a group that switched the voice boxes of 300 GI Joe and Barbie dolls. As befits a project affiliated with ®TMark, the critical content of BLO’s act was an alchemic stroke of humour and commentary. The protest lies within the ˜information alteration” of commodities that usually rely on their supposed virtues. The BLO offensive drew attention to the questionable labour practices of Mattel, manufacturers of Barbie, thereby undermining the perceptions on which Barbie’s popularity rests.” M/C Journal
