TikTok has cemented itself as a quintessential entertainment app, offering everything from funny skits and makeup tutorials to social commentary and news.
Without a sale to an approved buyer, the platform is expected to vanish from U.S. app stores by Sunday now that the Supreme Court unanimously upheld the the ban.
The decision came against the backdrop of unusual political agitation by President-elect Donald Trump, who vowed that he could negotiate a solution. It's unclear what options are open to Trump once he is sworn in as president on Monday. An official in the Biden administration told the Associated Press on Thursday that the outgoing administration was leaving the implementation of the law to the new administration.
TikTok has more than 170 million U.S. users. According to the Pew Research Center, that includes most teens and a third of adults. If you are an avid user, or a creator who relies on the platform for income, here's what you need to know about the ban and how to prepare for it:
What happens on Jan. 19?
A lawyer representing TikTok told Supreme Court justices last week that TikTok will ''go dark'' on Jan. 19 if the law isn't struck down.
What that means in practice is unclear currently, but the law bars app stores operated by Apple, Google and others from offering TikTok beginning on Sunday. Internet hosting services also will be prohibited from hosting TikTok.
Users should continue to have access to TikTok if it's already downloaded on their phones, but the app will disappear from Apple and Google's app stores — so new users won't be able to download it.
