There are women on the Internet. Did you know? Madison Avenue is just figuring this out, desperately looking for websites to stuff with female-targeted ad dollars. Lifetime, the cable network, just launched its own social network, mylifetime.com, with a lot of help from Glam Media's stable of female-centric blogs. Similarly, Warner Bros. announced entertainment and advice destination Mom Logic. Martha Stewart has launched Martha's Circle, an online ad network which represents other websites, and NBC Universal's iVIllage has struck a similar deal with Sugar Publishing. "It's kind of boring to say, but we really think content's king in this category," said Starcom's Jeff Marshall to AdAge. Boring, and false. The rule these days is sell the ads first, and find a place to put them later.
