March 21st marks 15 years of Twitter’s existence. The company traces its origins back to March 21, 2006 when Jack Dorsey published his first message on the platform at 9:50 p.m. Pacific Standard Time, which read: “just setting up my twttr”. Despite the anniversary, Twitter is still generally regarded as one of the new tech kids on the block and many other technology companies have been operating for a whole lot longer.
