The Disney/ABC series, which won't return for a third season, has had significant budget overruns in its first two seasons because of the anchor's repeated request to run tapings longer than their allotted time in order to get better content.
The longer tapings are compounded by the fact that "Katie" has more field producers and news staff than most lifestyle shows, the Hollywood Reporter said.
The overtime required to edit the extra content put the show over budget and led to the decision to air live four out of five days of the week. The fifth day is expected to be taped but be limited to the one-hour time allotment.
The show is scheduled to end when its initial two-year contract runs out and Couric will start a new job in 2014 as a global anchor for Yahoo!
