The article examines the phenomenon of code-switching in Internet discourse as one of the key strategies of modern digital communication. Theoretical foundations from R. Jakobson to P. Blom, J. Gumperz, Sh. Poplack, and C. Myers-Scotton are discussed, along with their application in online interaction. Based on examples from Instagram, Telegram, and YouTube, it is shown that code-switching is not a deviation from linguistic norms but a means of expressing emotions, irony, and identity, adapting messages to multilingual audiences. The study concludes that a hybrid norm of online communication is emerging within English-, Russian-, and Uzbek-speaking digital spaces.
