Four years ago, on October 27, 2022, Elon Musk officially completed his $44 billion acquisition of Twitter. What followed was one of the most dramatic transformations in social media history, turning the platform formerly known as Twitter into the app now called X.

The changes started almost immediately, with major staff cuts, policy shifts, and the introduction of paid verification through X Premium. The familiar blue checkmark system was overhauled, the platform's moderation approach changed, and features that had once defined Twitter were reworked or removed. For users, the experience of opening the app began to look very different.

Then came the rebrand. In July 2023, Twitter's iconic blue bird logo was replaced with the letter X, marking the end of one of the most recognizable brands on the internet. Musk has repeatedly described his ambition to turn X into an "everything app," expanding beyond social media into payments, video, creators, and other services.

Four years later, X remains a major platform for breaking news, internet culture, and real-time conversation, but its evolution has been anything but quiet. Between the rebrand, changing rules, new features, and ongoing debates about the platform's direction, the Twitter that existed in 2022 feels like a different era. And the wildest part? The timeline is still writing itself.
