Fireship

Fireship exploded to 3.5 million subscribers by pioneering 100-second tech explainers, a format 60% shorter than the typical coding tutorial yet retaining 85% viewer completion—outpacing Dave2D's average retention by 15 percentage points. Jeff Delaney's weekly "Code Report" series, covering AI tools and frameworks, attracts 2 million views per episode, making it the most efficient update for busy developers. His Firebase-based courses generate $4 million annually, proving niche content can rival general tech channels in revenue per subscriber.
