“The role of racism and social injustice in Coca-Cola’s removal of coca is corroborated by the attitudes that the shaped subsequent U.S. cocaine regulation movement. Cocaine wasn’t even illegal until 1914 — 11 years after Coca-Cola’s change — but a massive surge in cocaine use was at its peak at the turn of the century. Recreational use increased five-fold in a period of less than two decades. During that time, racially oriented arguments about rape and other violence, and social effects more so than physical health concerns, came to shape the discussion.” 
A short and abstract history of Internet with just right amount of technicality (for me at least). Mainly, two things were new to me. The first was that the documentary related the original conception of the Internet to the development of large centralized computers in 50s which demanded operators to work with them remotely. Second one was that at least 3 other networks (except ARPANET, military-research network) were fundamental in the development of Internet as we know it today: RAND military network in US, NPL commercial network in UK, and CYCLADES scientific network in France.
