"Over the past decade, the tweet has evolved from a simple 140-character text message to a rich canvas for creative expression featuring photos, videos, hashtags, Vines and more," Twitter product manager Todd Sherman said in a statement.

"So, you can already do a lot in a tweet, but we want you to be able to do even more."
