Now, her friends and family are launching a three-day Web media blitz in an effort to bring her home.
Kiirsi Hellewell, a friend of Susan Powell, said on "The Early Show" Monday she hopes millions of people will see Susan's name and picture online and come forward with information.
Hellewell said the idea is to canvas the Internet through Twitter, Facebook, MySpace, blogs, podcasts, e-mail and YouTube, among other outlets, to find Susan.
James Hofheins, one of the campaign organizers, has said there will also be a purple ribbon campaign, and Facebook users are being asked to change their profile pictures to a purple ribbon.
Susan's disappearance, Hellewell said, was against Susan's will.
