Sarah Palin helped "Today" maintain its winning streak against "GMA," even with the appearance of its own guest star Katie Couric.
NBC's "Today" widened its advantage over ABC runner-up "Good Morning America" by 23,000 viewers Tuesday, compared with the day before, according to the Nielsen Co.
"Good Morning America" brought Couric back to morning TV after her many years hosting "Today." Couric, now at ABC, is filling in all week at "GMA." Palin appeared as a "Today" guest co-host on Tuesday.
"Today" drew 5.5 million viewers, while "GMA" had 356,000 fewer people tuning in. On Monday, the gap dividing them was 333,000 viewers.
This morning-show rivalry has intensified as "GMA" chips away at the audience margin that has kept "Today" in first place for 15 years.
