Most big newspaper organizations have obituaries written in advance for almost every celebrity, whether or not that person is close to death. This is done so that if a celebrity does die unexpectedly, they can rush in, fill in a few details, and publish the obituary within minutes.
Of course, when people are involved, accidents do happen. Yesterday around 4:30PM EST, Bloomberg accidentally published their most recent obituary for Steve Jobs. Presumably, the obituary went live accidentally while the writer did touch-ups.
Steve Jobs, who had been battling pancreatic cancer over the past several years, is not dead yet.
