Twitter's mission has subtly shifted over the past several years. In 2014, the company's mission easily fit within the old 140-character limit: "To give everyone the power to create and share ideas and information instantly, without barriers."

Just as the social media company's character limit has evolved, so has the company's mission. Today, Twitter says it's goal is "to power positive global change by fostering respectful conversations, creating deeper human connections and encouraging diverse interactions among individuals and teams, across our organization, and on the platform resulting in a more globally inclusive culture and more globally diverse workforce."
