In spring 2020, pandemic-induced lockdowns significantly increased global internet traffic as people consumed more online content, especially video, which placed immense pressure on network infrastructures. In response, companies like Facebook were asked to reduce video quality to alleviate bandwidth strain. Surprisingly, when Facebook reduced video quality, they noted an unexpected increase in video watch time, particularly in countries like India, where many users relied on cell data plans. This revelation led to the development of a "Datasaver" mode tailored to users who frequently maxed out their data limits, highlighting the importance of experimentation and understanding user behavior. The situation underscored the value of adaptive strategies based on detailed user insights, challenging initial assumptions and resulting in a more personalized service approach.
