Reuters reports that Couric's new nationally syndicated series, "Katie," beat out debuts on Monday by Ricki Lake and Jeff Probst, according to Nielsen ratings.
The ex-CBS news anchor also beat out Steve Harvey's new talk show, which debuted last week.
Couric received a 2.8 household rating with her premiere, which featured guest Jessica Simpson. That rating was 250 percent higher than Lake's and 150 percent higher than Probst's, Reuters reports.
The former "Today" show co-host's new show also held the top slot in New York and Los Angeles. More specific figures will surface next week.
