Many of today’s most popular applications and operating systems have been around for a long time. This is a look back at version 1.0 of some of the most popular and widespread applications of today, many of them ranging all the way back to the 1980s.
So Let’s start with the first versions of Windows and Mac OS and move on to the applications from there…
Windows 1.0
Microsoft Windows 1.0 was launched on November 20, 1985. To be precise, the first release version actually had the version number 1.01. The first version of Windows was only available on floppy disks and you had to install it on top of DOS; Windows 1.0 was essentially an MS-DOS program.
Since Apple owned the right to have overlapping windows in the GUI, Windows 1.0 was stuck with using tiled windows (only dialog boxes could overlap windows).

Mac OS 1.0
The first version of Mac OS came bundled with the first Macintosh personal computers that were introduced on January 24, 1984. At the time it wasn’t even known as Mac OS, but simply as the System Software. Apple didn’t officially rename it to Mac OS until the release of version 7.6 in 1997 (although the name had started appearing on the boot screen since System 7.5.1).

Photoshop 1.0
Developed by the brothers Thomas and John Knoll and licensed to Adobe in September 1988, Photoshop 1.0 was released exclusively for the Mac in 1990. Thomas Knoll had started working on what eventually became Photoshop as early as 1987, initially as a tool for manipulating scanned images but it soon transformed into a full-fledged image editor. A Windows version of Photoshop was introduced in November 1992.

Word 1.0
Microsoft Word was released for the IBM PC on October 25, 1983. Although it was a character-based DOS program (albeit with mouse support), Word was the first word processor that showed line breaks and typeface markups (bold, italic, etc) directly on screen while editing.
The first Word to run on a GUI was Word for Mac, which was released in 1985 (it’s the one in the picture). Word for Windows was released in 1989 with the release of Windows 3.0.
An interesting side note is that MS Word was the first ever program to be distributed on disk with a magazine. A demo copy of Word was included with the November 1983 issue of PC World.

Excel 1.0
Microsoft Excel 1.0 was released for the Mac in 1985. It didn’t appear on Windows until 1987, after Windows 2.0 had been released. Excel was actually Microsoft’s second attempt at a spreadsheet program; it followed the relatively successful Multiplan, a spreadsheet program that was ported to a variety of systems such as MS-DOS, Apple II, Commodore 64 and more.

Internet Explorer 1.0
Internet Explorer 1.0 was released for Windows 95 on August 16, 1995. As most browsers of that time it was based on Mosaic, the web browser often credited with popularizing the WWW. IE was part of the Internet Jumpstart Kit in Microsoft Plus! (a pack of “OS-enhancing” applications) and was also included in the OEM release of Windows 95.

Firefox 1.0
Firefox is far younger than the other applications in this article, but we included it since it’s so popular today (and to balance out IE a bit). Mozilla released Firefox 1.0 on November 9, 2004, as the intended replacement for the increasingly bloated Mozilla Suite.
It was far from obvious that the browser was going to be called Firefox. During its development the project was first called Phoenix, but had to be renamed due to trademark issues. The new name after that, Firebird, clashed with the Firebird database server project, so finally the name was changed to Firefox, and that one stuck.
