Last week, the Senate passed the "Child Safe Viewing Act" (S-602), which directed the FCC to study possible new technologies that would allow parents to block access to content on a wide array of devices including DVD players, TV sets, set-top boxes, and wireless devices. In doing so, the bill expands the FCC's authority to cover media content on a number of platforms and may impact a number of voluntary ratings systems--including those used for movies and video games.
