Social media has been flooded with plain black images as celebrities and activists take part in the Black Out Tuesday #TheShowMustBePaused campaign - but there is growing criticism it is blocking important information.
People all over the world have been posting images and then disengaging from social media to show solidarity with US protests over the death of George Floyd.
The campaign was started by music executives Jamila Thomas and Brianna Agyemang as a "call to action" because "the show can't just go on as our people are being hunted and killed".
"Use this time on Tuesday to come together and figure out how we can hold our partners, colleagues and companies alike, accountable to come up with and execute a plan that actively supports and protects the very culture that it profits from," Brianna posted to her Instagram.
Celebrities including Jennifer Aniston, Nicole Scherzinger, Idris Elba, Kylie Jenner, Dwayne "The Rock" Johnson and Katy Perry have all joined the campaign, posting black images to their Instagram pages which reach millions of followers.
But some activists are concerned the posts will block out important information including protest updates and donation websites, making it "counterproductive".
"We know that it has no intent to harm but to be frank, this essentially does harm the message," mental health advocate and Black Lives Matter activist Kenidra Woods posted on Twitter.
"We use the hashtag to keep people updated. Please stop using the hashtag for black images!!"
Many people find information through searching hashtags such as #BlackLivesMatter but now it has been filled with black squares.
"When you check the #BlackLivesMatter hashtag, it's no longer videos, helpful information, resources, documentation of the injustice, it's rows of black screens," music artist Kehlani explained on her Instagram story.
Instead, those taking part in the campaign are being asked to not use any important tags and to continue to spread information about the movement.
Rappers Lil Nas X and Awate have also been critical of the movement on Twitter.
"I just really think this is the time to push as hard as ever," he wrote. "I don't think the movement has ever been this powerful. We don't need to slow it down by posting nothing. We need to spread info and be as loud as ever," Lil Nas X tweeted.
UK rapper Awate said: "Instead of this performance, we should find a way to unionise and innovate methods of supporting the struggles of our people under attack. Capitalism got us here. Let's try a collective approach".
In the United Kingdom, many television shows have also been finding ways to mark the day including Holly Willoughby and Phillip Schofield on This Morning briefly showing a black screen with the words "Black Lives Matter".
MTV planned to go silent for eight minutes, marking the amount of time the police officer knelt on George Floyd's neck, The Guardian reported.
