Het verhaal

HOE KEY
IS ONTSTAAN.

2003
2013

Keynote 1.0 shipped in January 2003 as Apple’s presentation software — built originally for Steve Jobs’ own keynote speeches. Jobs had ordered a replacement for PowerPoint because the tool he used onstage was not good enough for his own productions; Apple’s internal team built Keynote around cinematic transitions, typographic polish, and the kind of animations movie studios use. The format was so visibly nicer than PowerPoint that Apple released it to the public within a year.

The .key file went through the same 2013 iWork rewrite as Pages and Numbers — old .key files were bundles (folders disguised as files); modern .key files are ZIP archives containing IWA (iWork Archive) Protocol-Buffers blobs. Keynote-for-iCloud runs entirely in JavaScript. Presenters serious about visual polish (TED speakers, investor pitches, Apple WWDC itself) still write in Keynote and export PDF or DOCX for audiences on other platforms.

WEETJES &
TRIVIA.

01

Keynote was created at Steve Jobs' direct request in 2003 — he wanted a better tool for his own keynote speeches.

02

Apple WWDC keynote slides are Keynote files — the company literally uses its own software onstage.

03

A modern .key file is a ZIP archive of IWA (iWork Archive) Protocol Buffers — opaque outside Apple apps.

04

Keynote supports "Magic Move" transitions — objects smoothly animate between slides, a signature Apple effect.

05

Keynote is free and preinstalled on every Mac, iPad, and iPhone since ~2014.

STERKE PUNTEN &
BEPERKINGEN.

Beperkingen

  • Apple-only — Windows and Linux cannot open .key files natively.
