NEW YORK (AP) — The audience boost that the London Olympics provided for NBC’s “Today” show in its ratings battle with ABC’s “Good Morning America” was short-lived.

The Nielsen Co. said Monday that “GMA” beat “Today” in the ratings last week, the week after the Olympics concluded, by an average margin of 162,000 viewers. NBC was counting on the Olympics to provide a launching pad for its new anchor team of Matt Lauer and Savannah Guthrie, and it organized a series of concerts and visits by Olympians last week to keep up the momentum.
