The Other Agency has been tapped by trade show producer IDG World Expo to promote its 25th annual COMNET conference, scheduled for January in Washington, D.C.

COMNET is geared toward professionals in the communications and networking industries. “It’s a chance for us to deepen our relationship with IDG,” said Jim Rosenberg, president of the Newton, Mass.-based Other Agency, which has worked on other IDG properties, including magazines and Web sites.

The shop will develop a print, direct, e-mail and collateral support campaign that targets networking and information-technology professionals. “It’s a great opportunity to showcase our expertise in the technology arena,” said Rosenberg.

The Other Agency’s client roster also includes RSA Security, American Skandia, Barclays Global Investors and Revenio.
