Warner-Lambert and Listerine

Jeopardy on 14 Feb 09 seemed to suggest Listerine was invented at Johnson and Johnson. As wikipedia points out: First formulated by Dr. Joseph Lawrence and Jordan Wheat Lambert in 1879 as a surgical antiseptic, it was given to dentists for oral care in 1895 and it was the first over-the-counter mouthwash sold in the United States in 1914. The mouthwash was named in honor of Dr. Joseph Lister, a pioneer of antiseptic surgery.

Pfizer acquired Warner-Lambert to get Lipitor, but as wikipedia points out: [Listerine] is currently manufactured and distributed by Johnson and Johnson since that company's acquisition of Pfizer's consumer healthcare division in late December of 2006.
Pfizer closed down the Warner-Lambert Ann Arbor research facility. One of the developers of Lipitor was terminated.

Also on Jeopardy, a respondent on Chex cereals answered Ralston-Purina instead of General Mills.
