Zeitgeist of 1976

There was a Jupiter-Saturn-Uranus T-square in 1976. How did this aspect figure resonate with the zeitgeist - the "spirit of the age" - of that year?

In the field of politics, 1976 can be remembered as the end of an era and the beginning of a new one:

In China the Cultural Revolution ended, and its leader and founding father, Mao Zedong, died, marking the end of an era that had started in 1949.
The Vietnam war had ended with the fall of Saigon on 30 April 1975 and Vietnam was reunited in 1976.
Started in 1969, the so-called Détente between the Soviet Union and the United States, continued, as symbolised by the Apollo-Soyuz handshake in space in July 1975.
In November 1976, democrat Jimmy Carter was elected president, with a radically different program from its republican predecessors Nixon and Ford.

The following new and unique cultural phenomenon are worth mentioning:

Punk rock and New Wave, which emerged between 1974 and 1976 as a reaction against mainstream 1970s rock, and became major in 1977.
Irish rock band U2 was formed. The transits on Bono's birth chart for the day of the Jupiter-Uranus conjunction of 1976 are impressive: Uranus was transiting his natal Moon-Neptune conjunction and Jupiter was reaching his Venus-Mercury conjunction. It's interesting to note that Steve Jobs and Bono (U2's lead singer) were friends, and that U2 has partnered with Apple numerous times since 2003.
The first Star Wars was filmed in 1976, and would be released in 1977.
Evolutionary biologist Richard Dawkins published his book The Selfish Gene which popularised the gene-centred view of evolution and introduced the term meme.

It was also an important year in terms of technology breakthroughs, particularly in aerospace and computing:

the Concorde supersonic passenger airliner made its first commercial flight (its very first flight was in 1969).
the Viking 1 and Viking 2 spacecrafts successfully landed on Mars, and the Voyager program was preparing the famous Voyager 1 and Voyager 2 for a grand tour to Jupiter, Saturn, Uranus and Neptune (launched in 1977).
the space shuttle Enterprise was rolled out.
it marked the beginning of the personal computer revolution: Steve Jobs and Steve Wozniak founded Apple in April 1976 and introduced the Apple I, one of the first personal computers targeting the consumer market. One year later, in 1977, the first commercially successful personal computers were launched.
