Mark Zuckerberg's Banter With Users After Threads Launch Creates Waves

Threads was introduced as a clear spin-off of Instagram, which offers a built-in audience of more than two billion users.

More than 10 million people have signed up to Threads, Meta's rival to Twitter, within the first few hours of its launch, the Facebook parent's CEO Mark Zuckerberg said Thursday. pic.twitter.com/MbMxUWiQgp

Threads is the biggest challenger yet to Elon Musk-owned Twitter, which has seen a series of potential competitors emerge but not yet replace one of social media's most iconic companies, despite its epic struggles.

The app went live on Apple and Android app stores in 100 countries at 2300 GMT on Wednesday, and will run with no ads for now.
