BRUSSELS, July 30 (Reuters) - Both ChatGPT and ‌Roblox could potentially ‌be included by the European ​Commission in the list of very large online platforms or ‌search engines ⁠as defined by the Digital Services ⁠Act, Commision spokesperson Thomas Regnier said. Since ​both ChatGPT ​and ​Roblox have announced ‌user numbers above the DSA threshold, a designation is "definitely possible" and could "come sooner or ‌later", he ​said. Online platforms ​and ​search engines included ‌in the DSA ​lists have ​to abide by a series of ​rules ‌and obligations. (Reporting by Inti ​Landauro, Editing by ​Louise Heavens)
