Long-form storytelling and high production value helped increase average view duration, which directly boosted ad revenue rates.
Audience Growth and Brand Deals
Rapid audience growth opened premium sponsorship opportunities. In 2018, marketers increased spend on influencer campaigns aimed at kids and teens, benefiting creators in toy, family, and comedy verticals. Exclusive brand deals often provided multi-year contracts with minimum performance guarantees, stabilizing cash flow beyond advertising.

Revenue came from Super Chat, channel memberships, and direct fan funding, allowing top performers to exceed traditional ad income. Compliance with community guidelines became essential to protect long-term earnings.
