20th century 

Mass production brought automobiles and other high-tech goods to masses of consumers. Military research and development sped advances including electronic computing and jet engines. Radio and telephony greatly improved and spread to larger populations of users, though near-universal access would not be possible until mobile phones became affordable to developing world residents in the late 2000s and early 2010s.

Energy and engine technology improvements included nuclear power, developed after the Manhattan project which heralded the new Atomic Age. Rocket development led to long range missiles and the first space age that lasted from the 1950s with the launch of Sputnik to the mid-1980s.

Electrification spread rapidly in the 20th century. At the beginning of the century electric power was for the most part only available to wealthy people in a few major cities such as New York, London, Paris, and Newcastle upon Tyne, but by the time the World Wide Web was invented in 1990 an estimated 62 percent of homes worldwide had electric power, including about a third of households in the rural developing world.

Birth control also became widespread during the 20th century. Electron microscopes were very powerful by the late 1970s and genetic theory and knowledge were expanding, leading to developments in genetic engineering.

The first "test tube baby" Louise Brown was born in 1978, which led to the first successful gestational surrogacy pregnancy in 1985 and the first pregnancy by ICSI in 1991, which is the implanting of a single sperm into an egg. Preimplantation genetic diagnosis was first performed in late 1989 and led to successful births in July 1990. These procedures have become relatively common.

The massive data analysis resources necessary for running transatlantic research programs such as the Human Genome Project and the Large Electron–Positron Collider led to a necessity for distributed communications, causing Internet protocols to be more widely adopted by researchers and also creating a justification for Tim Berners-Lee to create the World Wide Web.

Vaccination spread rapidly to the developing world from the 1980s onward due to many successful humanitarian initiatives, greatly reducing childhood mortality in many poor countries with limited medical resources.
