*Among the network morning shows, NBC’s “Today” has grown roots at the No. 1 spot in the ratings – but according to the Wall Street Journal, the perennial second place operation at ABC is steadily gaining ground.

The “Today” show earlier this year celebrated its 800th week in the top ratings spot. During last month’s fall season premiere week, “Good Morning America,” with co-anchors Robin Roberts and George Stephanopolous, inched to within a daily average of 397,000 viewers of “Today,” according to the Journal. That compared to a Today viewer advantage of 1.1 million and 1.4 million during the same week in 2010 and 2009, respectively.

Last week, “Today’s” viewership lead on average was around 270,000, the paper said, citing preliminary Nielsen data.

“Today’s” ratings have rebounded in recent days, and it continues to dominate among the core viewers aged 25 to 54 years, the Journal said pointing to more preliminary ratings data. Still, NBC and its new owner Comcast will keep a close eye on “GMA’s” gains.

“Today” brought in $535 million in advertising revenue in 2010, up 5.6 percent from a year earlier, according to estimates from research firm Kantar Media. “GMA” took in $314 million from ads, up 6.3 percent, according to the Journal.
