Twitter is experimenting with raising the limit on tweets from 140 characters to 280 characters.
The company wrote in a blog post on Tuesday it was rolling out 280-character limit tweets to "a small group" of users who tweet in languages that may make it difficult to include everything they want to say.
"We understand since many of you have been Tweeting for years, there may be an emotional attachment to 140 characters – we felt it, too," Twitter product manager Aliza Rosen wrote. "But we tried this, saw the power of what it will do, and fell in love with this new, still brief, constraint."
Shares of Twitter rose more than 1 percent in extended trading following the news, CNBC reports, after declining more than 2 percent during the regular session.
