The document summarizes key findings from the Wave project, which has tracked social media trends globally over 7 years. It finds that while growth has been unprecedented, the true story is of social media's evolution in meeting fundamental human needs. Specifically, the 3 main points are:
1) Social media usage has grown from a niche activity to a global norm, driven by inherent human desires for connection and self-expression.
2) Smartphones have become the dominant internet-connected device, increasing their penetration nearly 70% from the previous Wave study.
3) Rather than just tracking trends, the project has learned to examine the underlying human motivations driving social behavior in order to provide more meaningful insights for brands.
