TV Content Ratings System Set to Expand to Web

The black labels that tell families what to expect from network television shows will start to appear on the Internet streams of those shows, too.

The expansion of the TV content ratings system is expected to be announced by the major broadcast networks on June 11. The ratings will be included in all episodic streams on Web sites like ABC.com and Fox.com by December, according to people with knowledge of the plan, who insisted on anonymity because it had not yet been made public. The announcement is an illustration of the ways that television networks are having to adapt to the Internet, where there has been a surge in the streaming of TV shows. Some sites, notably Hulu, already incorporate the content ratings into their online streams.
