Where 68,000 fits
Why 68,000 is special
It offered a flat 16-megabyte address space where Intel's contemporaries used segmented memory, which made it markedly easier to program. Losing to x86 anyway is a standard illustration that the better architecture does not necessarily win.

Related numbers & connections
The Motorola 68000 part number named a family, and the abbreviation 68k is derived directly from it.
The 68020 made the 68000 family fully 32-bit and added an instruction cache. The 68000's flat address space was easier to program than the segmented x86 of the same period, and it lost the market anyway.

Technology & computing
The 68000 gave programmers a flat address space while x86 required segment arithmetic for anything over 64 KB. It powered the Macintosh, Amiga, Atari ST and Mega Drive and still lost the market, because compatibility mattered more than elegance.
