Microsoft became the latest company to drop a long-standing practice of distributing its full quarterly financial results via newswire in favor of issuing a shorter release pointing people to its investor relations Website to find them.

The move, announced in advance of the software giant’s first-quarter fiscal 2011 results on Oct. 28, puts Microsoft in a small but growing group of companies, including Google, that have shifted their IR practice to take advantage of Securities and Exchange Commission guidance that enables companies to rely more on disclosure via their corporate Website to communicate with investors.
