James at the Forty blog tells us where various company names come from. A few highlights:
Adobe: from the name of the river Adobe Creek that ran behind the houses of founders John Warnock and Chuck Geschke.Note how most of the names of the established companies in James' list are either proper names, are derived from facts about the founders, or are derived from acronyms.
Canon: Originally (1933) Precision Optical Instruments Laboratory the new name (1935) derived from the name of the company’s first camera, the Kwannon, in turn named after the Japanese name of the Buddhist bodhisattva of mercy.
Nokia: started as a wood-pulp mill, the company expanded into producing rubber products in the Finnish city of Nokia. The company later adopted the city’s name.
