What is billanthropy?

Question

I failed to have the meaning of "BILLANTHROPY" is it a new word to designate "the charitable man possessor of milliards of dollars?

Answer 1

No. It doesn't just refer to any very rich man. It is a portmanteau word, an artificial combination of two words (bill + [phil] anthropy) coined by the Economist magazine in 2000 to mean the large-scale philanthropic activities of Microsoft billionaire Bill Gates and his wife.
