Global ad revenue reached $139.0 billion in
the third quarter, up 4.3% over the year-earlier period, according to Nielsen's

Ad spending in the third quarter was buoyed
by the 2012 London Summer Olympics, as well as the run-up to the U.S.
presidential election. In the U.S., ad spending in the third quarter was up 10.2% over the year-earlier period.
