Twitter (now X) Co-founder Jack Dorsey has revived Vine, the six-second looping video-sharing app. He has funded the new project called 'diVine', which provides access to over 100,000 archived Vine videos. The app won't allow AI-generated content and flag its posting. Vine was a popular social media app, owned by Twitter, that launched in 2013 and shut down in 2017.
