Well, you didn't say when you were born. But let me have a go: Inflation theory (1980), Gluons (1979), Experimental verification of quarks (mid 1970's), Quantum Chromodynamics (1960, modern version 1975), Quantum Computing (1982), Spintronics (1980s), Josephson effect (1962), SQUIDS (1964/1965), Semiconductor Photolithography (1982), Nanotechnology (1980s), high temperature superconductivity (1986). Nothing interesting happened after 1994 because of the invention of the Spice Girls and because the eighties were over and everyone became obsessed with having answers immediately and looking it up on the web instead of reading books and so on. (It's just possible that this is when I gave up reading books and so I don't know about anything that happened since then. But I'd rate that possibility at less than 10% based on a back of the envelope calculation.)
