Federated Media is an advertising broker partner for many top tech tier sites.  They power the advertising for TechCrunch, Silicon Alley Insider, Mashable, You’re the man now dog, AppleInsider, ReadWriteWeb, VentureBeat, TechDirt, etc.  To date, Federated Media has raised $57.5 million.

Federated Media (FM) has lost a number of partners to acquisitions and poaching.  Digg was a partner of FM before Microsoft signed a deal with them.  Ars Technica was a partner of FM before Condé Nast bought them out.  Another Federated ad partner, Sphere was picked up by AOL.

Now GigaOm will be stepping down from FM to sign with IDG Group.  IDG’s Network includes CIO, Computerworld, JavaWorld, Linuxworld, Macworld, PC World, etc.

In related news, Federated Media is also slashing advertising rates in order to adapt to rough economic advertising conditions.  TechCrunch’s CPM has been dropped from $36 to $23.40.  Silicon Alley Insider’s weekly square button ads have been dropped from $630 to $409.50.
