Caitlyn (formerly known as Bruce) Jenner may be a former Olympic-gold decathlete, but the 65-year-old broke a very different kind of record Monday. Jenner, who has transitioned to life as a woman, revealed her new name and look on the July 2015 cover of Vanity Fair, along with a Twitter handle to accompany her new identity. Jenner shattered Twitter records with her debut, earning a million followers in the fastest time ever and sending the “CallMeCaitlyn” hashtag trending worldwide.

Data acquired for International Business Times by Brandwatch reveals the seismic social media impact of Jenner’s Vanity Fair reveal. In just the five hours following the release of the magazine cover on Twitter, there were over 152,000 mentions of Jenner and the photos on Twitter, via “CallMeCaitlyn” and other related hashtags. Women dominated the Twitter conversation, with female users authoring over 76 percent of relevant posts. The Twitter traffic peaked at 12 p.m. EDT.

Of all the hashtags, “CallMeCaitlyn” was by far the most popular, with over 144,835 mentions by 4:30 p.m. EDT on Monday. “Caitlyn Jenner” was a distant second at 12,490 mentions. Rounding out the relevant hashtags were “BruceJenner” at 2,511 mentions, ”GirlsLikeUs” at 1,973 mentions, and “VanityFair” at 1,469 mentions.

Jenner’s Twitter handle also broke the Guinness World Records mark for the fastest Twitter handle to reach 1 million followers. The “Keeping Up With the Kardashians” star did so in less than four hours and 30 minutes, according to Reuters. Jenner displaced the previous record holder, President Barack Obama, who reached 1 million followers in five hours only last month.
