LONDON — U.K.-based media research company Screen Digest has bought Californian outfit Adams Media Research for an undisclosed amount of cash and stock.

The Carmel-based company was set up in 1993 by Tom Adams to research the impact of digital technologies on the entertainment biz.

It publishes monthly newsletter Hollywood Aftermarket, and provides strategic and financial consulting for entertainment and new media companies.

Adams will continue as the president of AMR and will join the board of directors of Screen Digest. Allan Hardy and Ben Keen, Screen Digest’s chief analyst since 1997, will join Adams on the board of AMR.

The two companies already co-operate on online service Video Intelligence, which supplies data on the homevid sector.

After the merger, which is expected to be finalized by the end of this month, the new company will expand this service to include TV, film, games, mobile and broadband.

The companies have already started developing several new research services. The first of those, Global Media Intelligence, is an online service for media-focused institutional investors, which covers TV, films, video games, mobile media, home entertainment and broadband.
