In 2009, Twitter introduced a blue check mark to indicate that a profile is "verified." This mark shows other Twitter users that this account genuinely belongs to the person whose name it's in, and not to a parody account or troll.
The feature was introduced following a lawsuit from St Louis Cardinals manager Tony La Russa, after he was impersonated on the platform.
