The Top Ten
1 Joe Biden - Twitter

He was elected president on November 2020 & then in 2021, during the Capitol protests (which broke out in riots & 4 deaths from gun violence), Donald Trump was permanently suspended on Twitter & around that time, he matched Biden, giving him a whopping 12M on Twitter in just 24 hours! Yet Biden before that gained 7.5M followers in 3 weeks due to his electoral win. A historic 24 hour record like no other account anywhere, so he really grew a huge following like no other person. His account really broke the internet & is going down in history for such matters.

2 Jennifer Aniston - Instagram

On October 15th, 2019, Jennifer Aniston, known for playing Rachel Green in Friends, joined Instagram. Her 1st post was a reunion with the cast of Friends in a selfie, which was something we waited 15 years for.

Yet she set multiple records, formerly including the 1st 1M followers at the fastest time ever for Instagram, in 5 hours 16 minutes (316 minutes), which was 29 minutes faster than the 1st 1M Prince Harry & Meghan Markle got from their debut.

She gained 20M followers in 37 days & went up to 27M after New Year’s Day 2020 & now she has over a whopping ~36M followers.
