In what is thought to be the first public interaction to originate from Apple's official corporate Twitter account, the company on Friday posted a promoted-only tweet inviting users to tune in for next week's special event.

The promoted tweet offers basic information about the Sept. 7 event and includes a link to Apple's live stream, which is anticipated to go live shortly before the keynote kicks off next Wednesday.

Today's tweet also contains a custom Apple logo emoji and the hashtag #AppleEvent, the latter being a bid to spark public discussion of the upcoming announcement expected to bring news of new iPhone, Apple Watch hardware and, potentially, Beats headphone hardware.

Apple seems to be taking full advantage of the social media platform's notification feature set, as users who retweet today's promoted tweet are automatically signed up to receive a reminder on event day.

Interestingly, Apple opted to send the message as a promoted-only tweet, meaning it only appears in timelines of users specified in Apple's advertising campaign agreement. Followers of the @Apple account might see the post pop up in their feed if they are part of the targeted audience, though exposure is not guaranteed.

Apple's @Apple Twitter account was updated earlier today after lying dormant for five years. The corporate account joins a family of Apple Twitter handles maintained for customer support and promotion of various products like Apple Music, the App Store and iTunes.
