Business?

What’s business?
What does it mean ‘business’?
What’s the origin of this word?

Flying from Barcelona to Zurich (with more than one hour of delay) I was reading the ‘swiss magazine’ and there were the answer to these questions.:

“In economics, business is the social science of managing people to organize and maintain collective productivity toward accomplishing particular creative and productive goals, usually to generate profit.”

“The etymology of ‘business’ refers to the state of being busy. In other words, to be busy is to be doing commercially viable and profitable work.”

“The term ‘business’ has at least three usages:

• the general usage (above)
• the singular usage to refer to a particular corporation
• and the generalized usage to refer to a particular ‘market’ sector, such as the ‘record business’, the ‘computer business’ of the ‘business community’, the community of suppliers of goods and services”
