Logos changed many times during the years at Burroughs. In some cases liberties seem to have been taken with the color and look of the logos, often in locations outside the U.S. The following logos were the most common..
American Arithmometer Company - Used until about 1905
Burroughs - Early - note the slash "o"
Burroughs underlined - Another early symbol
Circle B (RED)- Used from 1940s until about 1968
Circle B with Burroughs spelled out - Also used from 1940s until about 1968
"Circle B" plus the "Wherever There's Business...." trademark from a 1973 Advertising Department document
"Electronic" Burroughs - Used from 1985 to 1986 (merger date)
