In late March FOLIO: reported that the print editions of InformationWeek and CRN, housed in UBM’s Tech Group, were to be shut down as part of the company’s ongoing efforts to shift its strategic focus on events and digital. The layoffs predicted in that story have begun today, say several sources.

The layoffs were originally expected to begin tomorrow, with sources saying they’d be significant, anywhere from 100 to 300.

Exact numbers remain unconfirmed, and a UBM spokesperson did not immediately respond to a request for comment, but an official announcement is said to be forthcoming today.

Offices on the West Coast and in New York are getting the news now, say several sources, and it appears editorial and central creative will be hard hit.

The Manhasset, NY offices, where central services are located, are a "blood bath," says one source. According to FOLIO:’s earlier story, those positions were said to be planned for outsourcing.

Update: According a release, UBM Tech will stop producing print publications as of July 1, 2013. InformationWeek will continue online. Test and Measurment World and Advanced Trading will be shut down and the group will also close four smaller events.

"Traditional b-to-b media has changed dramatically in recent years," says UBM Tech CEO Paul Miller in a statement. "A lot of what worked in the past is no longer viable."

Going forward, UBM Tech says it will pursue a model that blends its live events with digital community efforts. Layoffs associated with the shutdowns and elimination of print were not mentioned in the release.

Update 2: According to a post to the company’s wiki by UBM Tech CEO Paul Miller obtained by FOLIO: the restructuring followed a 3-month strategic review period. Ed Grossman (president of business technology media), Kathy Astromoff (CEO, UBM Electronics) and Scott Vaughan (chief marketing officer) have decided to leave the company after turning down offers for other internal positions.

Additionally, Amandeep Sandhu, VP of audience engagement and analytics will head up a new customer insights team and Kelley Damore has been promoted to chief community officer. 

The Channel group is currently undergoing a similar strategic review, which has been extended until the end of the second quarter.
