PageMaker (1987) 79 Publishing Windows OS2

Aldus PageMaker, later Adobe PageMaker, is a desktop publishing program for Mac and Windows. First released in 1985, PageMaker was the first desktop publishing program for the Macintosh. It was followed over a year later with the release of 1.0 for the IBM PC. The PC version was a notable application as it was one of the few rare applications which would run under Windows 1.x. PC PageMaker 1.0 bundled a runtime version of Windows. This enabled MS-DOS users who had not decided to buy Windows to run PageMaker. Aldus skipped version 2.0 on the PC to bring version number in sync with the 3.0 Mac product.

Sidekick (1984) 16 Utility PIM OS2

Borland Sidekick is a DOS based PIM (Personal Information Manager) and one of the first widely-used TSR (terminate and stay resident) programs. The key feature of Sidekick was that one could use Sidekick's utilities while using most other MS-DOS applications. This was important because MS-DOS had no built-in multi-tasking or task switching capabilities.
