The mystery of Wall Street was compromised just a bit when Bloomberg News confirmed a breach of ethics and privacy on Friday afternoon. To the financial industry's alarm, Bloomberg journalists have for years been monitoring the company's data terminals—found in nearly every banking and trading company—for user activity. They monitored what functions of the service subscribers were using, including corporate bond trades and equities indexes. The dustup came to light after a reporter pointed out to a Goldman Sachs partner that he had not logged into his Bloomberg terminal lately. Oops.
