Twitter Hashflag for October 18 'Unleashed' Apple Event Now Live

Apple also uses a #AppleEvent hashtag on Twitter. After today's announcement, new artwork was added to reflect the "Unleashed” event.

The hashflag update features a transition from light to dark blue, which matches the invitation artwork. Apple uses hashflags in order to increase event visibility and create hype on social media.

Apple uses custom Twitter hashflags from late last year. Agency Creative research suggests that they can be as expensive as $1 million.

Apple's "Unleashed", Monday October 18th, will be the event. It is expected that it will focus on new MacBook Pro models 14- and 16-inch.
