PALO ALTO, U.S. -- Facebook founder Mark Zuckerberg blamed the rise of ByteDance-owned TikTok and other rivals, along with heavy investment and a changing online advertising market, for a disappointing earnings report that wiped out a fifth of his company's market value on Wednesday.
The company, which recently renamed itself Meta Platforms, reported weaker-than-expected fourth-quarter earnings as user growth slowed in the Asia-Pacific -- its largest market -- and the user base logged little growth or declines elsewhere.
