Twitter 10th Birthday

As Twitter marks its 10th birthday somewhat of an awkward child, having become a powerful communication tool but still struggling to win users and reach profitability. Since making a star-quality entrance a decade ago, Twitter has become a must-have tool for journalists, activists and celebrities but has struggled to show it can expand beyond its devoted "twitterati" to become a mainstream hit.

Monthly active users remained stuck at 320 million at the end of 2015, Twitter has failed to keep pace with fast-growing rivals such as Facebook, which is only a few years older but has eclipsed the billion-user mark. While Facebook has evolved with new features, Twitter has changed little since it began. This year, Twitter priorities include making it more intuitive to use; live-streaming video, and making it safer for people to freely express themselves on the platform.
