Reading guide
Robin uses Google, Tripadvisor, and Agoda as examples. Google used to be the first layer, search; Tripadvisor the second, reviews; and online travel agencies (OTAs) the third. But Google keeps moving downstream, forcing OTAs to move upstream. The quoted second half lists four characteristics of internet businesses: a natural tendency toward monopoly, the need for sustained high growth, a disruptive nature that lets one expansion support the next, and greater pressure to turn a profit amid a worsening market environment. As a result, internet companies expand horizontally and vertically. Their thinking shifts from “What can I do?” to “What should be done?” That is why technology giants move into finance, automobiles, and healthcare.
