Starting today, you’ll notice we’ve updated the design of Twitter’s little blue bird. From now on, this new bird will be the universally recognizable symbol of Twitter. There’s no longer a need for text, bubbled typefaces, or a lowercase “t” to represent Twitter.
Inspired by a brand focus on simplicity, the new #Twitterbird also reflects our goal to transcend borders and reach every person on the planet with our service. Likewise, one powerful way to extend the reach of your brand is to integrate Twitter assets (including our buttons, your username handle and relevant #hashtags) across your marketing channels. Use our brand update as an opportunity to reassess how you’re promoting your Twitter presence to grow your followers and increase engagement.
