When Acronyms Don't Work

Would anybody search Intrenational Business Machines when wanting information about IBM? Likewise does anyone know that NBC stands for the Natioanl Broadcasting Company? Last night a student said he had a problem finding the company profile of the automaker BMW in Business Source Premier. It turns out that this company is listed under the German name Bayerische Motoren Werke AG. So I found out that acronyms don't work all the time.
