WASHINGTON--First Lady Michelle Obama marks the Wednesday first anniversary of her main agenda item--combating childhood obesity with her "Let's Move" campaign--with a speech in Atlanta and a media blitz.

Speaking at a print reporter lunch Tuesday about "Let's Move," Mrs. Obama said, "Tomorrow is the actual anniversary, and to kick it off I'm going on The Today Show and Regis and Kelly. Never done that before. But we're introducing a Public Service Announcement campaign as part of our efforts to get more information into the hands of parents. And we've worked with the Ad Council to generate these very clever and appealing ads, just giving parents some tips on how do you get your kids moving, how do you have conversations about healthy eating in ways that connect with communities of all kinds?

"And we've got 33,000 media outlets that are going to have these PSAs. They'll start airing over the next couple of weeks. And they have the potential to reach over 200 million viewers. So we're pretty excited about that.

"And then after I appear on those shows, I'm going to fly to Atlanta and spend time at one of the schools. But I'm there to give what I think is -- what feels like the right kind of anniversary speech, focusing on the parents, focusing on us.

"Because ultimately, Let's Move is about what I just said -- it's about parents and communities changing the demand."
