Twitter has long been known for its 140 character limit for status updates, but the company recently announced that Tweets will now be more than just 140 characters. Yes, Twitter is introducing expanded tweets. According to the Twitter blog:
"You've probably expanded Tweets before to play videos from YouTube or see photos from Instagram. Now, a diverse and growing group of new partners like the The Wall Street Journal, Breaking News, and TIME also deliver rich content inside Tweets containing a link to those websites."
In short, now when any of these partners share a link to content, you'll be able to see the headline and even a snippet or image from the article.
