TikTok, Twitter, Meta Face Countdown to Comply With West’s Toughest Content Law

BRUSSELS—The world’s most far-reaching digital-content law will oblige 19 social-media, search and e-commerce services to comply with strict new rules by late August. 

Companies including Apple Inc., Amazon.com Inc., Meta Platforms Inc. and Alphabet Inc.’s Google had one or more of their services listed Tuesday as “very large” online platforms or search engines by the European Union’s executive arm. The designations, which also include Bytedance Ltd.’s TikTok and Twitter, mean the clock starts on a four-month countdown to get into compliance with a slew of rules in the new law, called the Digital Services Act.
