It appears morning show king Today has some major competition in Good Morning America following a spike that has narrowed the ratings gap to the smallest margin in four years, according to a report by Bloomberg.

Today — whose co-host line-up changed in June when Meredith Vieira’s spot on the show was filled by Ann Curry — still leads by at least 500,000 in total viewers and in the advertiser-attracting 25-54 demo. But GMA is hot on its trail. Today has averaged 5.03 million viewers daily since June, up 6.7 percent from a year earlier (according to Nielsen), while GMA has experienced a 15 percent boost, averaging 4.46 million.

It’s undeniable to regular GMA viewers that even though Diane Sawyer and Charles Gibson were big losses for the morning show, hosts George Stephanopoulos and Robin Roberts have brought a new flavor. A GMA EP gave credit to revamped cooking and entertainment segments under the new hosts, but is it more than that, readers? Tell us in comments.
