Last week, "GMA" beat "Today" by more than 600,000 viewers and 100,000 adults age 25-54, winning its third week in a row. This is the longest streak the show has had in both categories in 18 years, reports The Hollywood Reporter.

GMA and "Today" have had the narrowest margins in viewers and demo since the 1994-1995 season.

Roberts started her leave on Aug. 30. While she is receiving treatment, the show will have guest co-hosts to  fill her seat.

Someone on GMA this morning told us that protecting the subways from future floods would cost $10B, saying that this is super expensive. Please consider placing that in the context of the $1T cost of the Iraq invasion...

Those on GMA seem to actually enjoy each other and the weekend crew does just as well.
