Five major entertaiment trade bodies have teamed to form the Coalition of Entertainment Retail Trade Associations (CERTA).

Five major entertaiment trade bodies have teamed to form the Coalition of Entertainment Retail Trade Associations (CERTA).

CERTA -- comprising the Digital Media Assn., the Interactive Entertainment Merchants Assn., the National Assn. of Recording Merchandisers, the National Assn. of Theatre Owners and the Video Software Dealers Assn. -- plans to publicly address common concerns such as piracy and ratings awareness.

The idea to form CERTA sprung from a daylong Federal Trade Commission workshop in October 2003, attended by the trade groups, that addressed parental-advisory label guidelines for videogames.

There are no plans to appoint a president for CERTA. The heads of each trade group will work together.

An announcement about a lobbying effort relating to piracy is expected from the new group next week.
