British vs American Usage
Differences
No significant semantic difference. Historically, 'billion' meant a million million (1,000,000,000,000) in UK English and a thousand million (1,000,000,000) in US English, but the US definition is now universally used in finance and media worldwide, including the UK. The term 'billionaire' follows this modern standard.
Connotations
Similar in both variants. May carry slightly stronger connotations of 'self-made' entrepreneurship in American media, and slightly stronger historical/conservative wealth connotations in some UK contexts, but the distinction is minimal.
Frequency
Equally frequent in both varieties due to globalized business and media.
