The New York Times DealBook’s Michael J. De La Merced reports that the S.E.C. has given the green light to companies that want to use outlets like Facebook and Twitter for important releases and announcements. The decision is in response to an investigation involving Netflix, where CEO Reed Hastings posted a message about his company using his personal Facebook feed. In order not to violate Regulation Fair Disclosure, investors must be alerted to which outlets will be used.
