Now, a new hashtag has been created #Twitterblackout for thousands of people on Twitter who are blacking out their profile picture on the social media platform.
The virtual protest explains that it is for those who want "to present that they are opposed to the result of Donald Trump becoming president."
In a show of unity, many have followed suit by replacing their profile pictures with a plain black square.
Many also included the hashtags #NotMyPresidentt and #ImWithHer to show their continued support for Hillary Clinton.
His election comes despite Hillary Clinton winning the popular vote, but still losing the presidential election in one of the most astonishing upsets in US political history.
