US-world politics: How TikTok grew from a fun social media app for teens into a potential national security threat | Timeline [Video]

SAN FRANCISCO — If it feels like TikTok has been around forever, that’s probably because it has, at least if you’re measuring via internet time. What’s now in question is whether it will be around much longer and, if so, in what form?

Starting in 2017, when the Chinese social video app merged with its competitor Musical.ly, TikTok has grown from a niche teen app into a global trendsetter. While, of course, also emerging as a potential national security threat, according to U.S. officials.

On April 24, President Joe Biden signed legislation requiring TikTok parent ByteDance to sell to a U.S. owner within a year or to shut down. TikTok and its China-based parent company, ByteDance, filed a lawsuit against the U.S., claiming the security concerns were overblown and the law should be struck down because it violates the First Amendment.
