BBC News - Microsoft fined by European Commission over web browserMicrosoft has been fined 561 million euros ($731m; £484m) for failing to promote a range of web browsers, rather than just Internet Explorer, to users in the European Union (EU).
Almunia absolutely spanks them, giving them a half a billion fine. Good on them too, sends a nice clear message to others. Comply with your commitments or we'll fine the bejesus out of you.
