Last week, the SEC announced a change to its rules for social media, permitting companies to use social media channels like Facebook and Twitter to announce important and timely news, rather than "just" the company's website or via a news release. The companies just have to tell investors which social media outlets will be used in the future, so that investors have fair notice of where to tune in to get the latest information.
What's notable about the change is not just that social media will become a permitted channel, but that given the speed of social media, it may have just become the necessary go-to channel. In fact, last week may mark the turning point for when Twitter went from being "just" a social media platform, to being an essential primary source of key news and information!
