Elon Musk officially became the owner of Twitter despite the turmoil during its buyout process. At one point, it seemed that Musk would give up finalizing the deal, but eventually it was finalized. Musk's first decisions after buying Twitter were controversial as four executives were dismissed almost immediately, including former CEO Parag Agrawal. The way Twitter works itself is also going to change significantly.
It turns out that Elon Musk is considering returning the Vine option to Twitter. This is an option known to Twitter users with longer experience, as it is part of the portal used to share looping videos. Vine finally closed in 2016, but Musk is considering reintroducing this option, as confirmed by a poll on Musk's official Twitter account. The results of the poll indicate that nearly 70% of people would like Vine to return to Twitter, so we can expect that Musk will try to restore this option to the portal.
