RCA “invented” the color TV in 1953 (following a 1940 parent), the first color broadcast was performed in 1965, and color TV sales only exceeded B&W in 1972: ~20 years Magnetic tape recording for video was invented in the 1950s but saw adoption from 1976 onward in the mass market: ~20 years TCP/IP was standardized in 1978 after ten years of ARPANET development. Mass adoption happened from 1995 onward: ~20 years First commercial cell phone prototype was in 1973, 1G networks opened in 1983 in the US, but GSM norm adoption picked up from 1991 onward: ~20 years The 20-year cycle is actually pretty robust - see the diffusion of innovations framework (Rogers, Christensen, etc). In blockchains, databases existed since the 1960s, public-key cryptography since the 1970s, and P2P tech since the late 1990s. But 2014 was when the first smart contract platform we know as Ethereum was released. We’re barely ten years in and still missing a few blocks for mass adoption incl. AA, UX, TPS, etc !remindme 10 years
