In the U.S., Aquafresh is GSK 's fifth biggest-spending brand -- after Advair, Lovaza, Sensodyne and Alli -- spending $41.9 million on advertising in 2010, although that was a drop of 23% over the previous year.

Most of GSK 's revenue -- 82% -- comes from its pharmaceutical business, and the rest from consumer products like toothpaste.
