Anything with "correction" (ie: originally used with white/black super-messy "correction" ribbons, and has the bichrome label "black, silver, white or white/red") will be very late 70's through the 80's. This *could* be 1987, and I think it probably is, because I know that correction started about 1978-9 for Brother, so it probably started around then for other manufacturers too. If someone knew for sure when those awful black/white ribbons were introduced *exactly*. you could pin it down more precisely, but right now, that's as good as we've got.

Arendt’s two-volume work The Life of the Mind, published posthumously in 1978.

In 1978, she became one of the first women ever to write and direct a comedy feature–Rabbit Test, a cult classic about a man (Billy Crystal) becoming pregnant.

In the liner notes of “Ambient 1: Music for Airports” (1978), Eno wrote, “Ambient Music must be able to accommodate many levels of listening attention without enforcing one in particular; it must be as ignorable as it is interesting.”

In 1978, he started to use the term “ambient music”: the concept stretched back to describe “Discreet Music” and the work of earlier composers, like Satie, who coined the term “furniture music,” for compositions that would be more functional than expressive.

Eno heard about No Wave, then the dominant style for downtown bands who were taking punk to its logical extremes—abandoning song form, playing entirely outside of formal tunings, and foregrounding noise over signal.

As a songwriter and producer, he worked with Olivia Newton-John from 1971 through 1989. He wrote her number-one hit singles: "Have You Never Been Mellow" (1975), "You're the One That I Want" (1978 duet with John Travolta), "Hopelessly Devoted to You" (1978), and "Magic" (1980). He also produced the majority of her recorded material during that time including her number-one albums, If You Love Me, Let Me Know (1974), Have You Never Been Mellow (1975), and Olivia's Greatest Hits Vol. 2 (1982). He was a co-producer of Grease (1978) – the soundtrack for the film Grease.
