Elon Musk buys the domain name of his 18-year-old startup
Billionaire entrepreneur Elon Musk on Tuesday bought the domain name X.com, which belongs to a now-defunct startup he founded in 1999. X.com merged with another startup Confinity in 2000, which later rebranded as PayPal in 2001. Musk hasn't revealed how he plans to use the newly-purchased domain name.
