Founders, Product Leaders & Media Theorists - Interest Media Shift

Looking for experts on “Interest Media vs Social Media” paradigm shift I’m working on a piece exploring the idea that traditional social media is evolving into “interest media,” where algorithms prioritize user intent and niche interests over social graphs. How do you define “interest media” in contrast to social media? What are the biggest behavioral shifts you’re seeing in users? Is this a complete replacement or an evolution of social platforms? Requirements: Founders, product leaders, or media theorists with experience in content platforms or recommendation systems.
