IDG’s TechNetwork, a leveraged collection of technology Web sites, has added GigaOM [1], the marquee tech site founded by Om Malik, to the ad network.

The network, which was launched [1] in March, averages 40 million unique visitors and 120 million page views per month.

Comprimised of non-IDG properties, the network is closing in on 200 sites serving “tech enterprise, enthusiast, and gamer/entertainment audiences.”

A wide range of tech marketers—including Dell, AT&T and Intel—have bought advertising  on the network, and IDG said revenue—with growth in the “six figure range” per month, according to an IDG spokesperson—has “grown eightfold” since March.
