Reed Business Information has become the latest publisher to reorganize into market-focused divisions. The company announced Wednesday the creation of four groups: business media, entertainment, construction and BuyerZone, a lead generation business.

The reorganization was a result of Chicago division president Jeff Greisch’s announcement that he is leaving the company at the end of the first quarter, RBI said.

It was not immediately clear if any products would be shut down or if any layoffs are associated with the reorganization. An RBI spokesperson declined to comment.

The business media group will be headed by CIO Jeff DeBalko, who will take on the added responsibility of group president. The group consists of several properties, among them RBI’s publishing group (including Publishers Weekly), the television groups (including Broadcast & Cable), RBI’s Boston-based properties (including Design News and Test & Measurement World) and RBI Interactive. Mark Finkelstein, president of RBI’s Boston operations, will now oversee its Chicago-based engineering titles, too.

The construction group will be led by Reed Construction Data CEO Iain Melville. It will comprise of several properties including Building Design + Construction and Custom Builder.

The Los Angeles-based entertainment group will continue to be headed by Variety president and publisher Neil Stiles. The BuyerZone group will be led by Mie-Yun Lee, who has been promoted to the newly-created position of group president.

In December, RBI parent Reed Elsevier called off the auction of its b-to-b publishing arm, blaming the down global markets. Bidding had reportedly fallen from approximately $2 billion to $1 billion.

Late last week, Penton Media reorganized around 13 market-focused segments, grouped under five umbrella groups. In recent months, similar reorgs have taken place at Source Media and F+W Media.
