# Information cascades create power law distributions in culture because consumers use popularity as a quality signal when choice is overwhelming

When confronted with near-infinite content choices, consumers need filters. One of the most powerful is popularity — people assume that other people's choices contain valuable information ("the most popular stuff must be popular for a reason"). This creates an information cascade: a positive feedback loop where early popularity amplifies into extreme dominance.

The mechanism is well-documented experimentally. Salganik, Dodds and Watts' MusicLab experiments (2006) showed that when people could see what others were listening to, popularity distributions became far more extreme and unpredictable than when they chose independently. Small early advantages snowballed. The same songs could become massive hits or complete obscurities depending on initial conditions. This means hits require a quality threshold but their ultimate success is heavily influenced by luck and timing.

Empirical evidence across entertainment media shows persistently, and sometimes increasingly, extreme power-law-like distributions:

- **Netflix series**: Distribution of global demand for top Netflix series became more skewed between 2018 and 2022, with the top hits becoming relatively bigger compared to the average (Parrot Analytics data)
- **Spotify**: 100,000 new songs uploaded daily; a tiny fraction capture nearly all streams
- **U.S. box office**: Power-law distributions in theatrical returns persist despite changing distribution models
- **Streaming subscriber acquisition**: Top 10 titles on streaming platforms represent 10-50% of demand but 50-80% of gross subscriber additions (Parrot Analytics, Q1 2023)

The implication is structural, not cyclical. As content supply increases toward "infinite" (GenAI will accelerate this), the tail gets longer, the middle hollows out, and the relative value of hits increases — even if their absolute size doesn't grow. The few hits that break through the noise become more valuable than ever, but their emergence remains largely unpredictable.

This creates a fundamental challenge for studios: you can't just "make the hits." The more the industry concentrates resources on trying to engineer hits (through franchises, existing IP, star power), the more it faces franchise commoditization — when everyone pursues the same strategy, the strategy ceases to differentiate.
