Why 1995 is special

Amazon and eBay both launched, and Windows 95 shipped with the internet as an assumed feature rather than an add-on. The combination is why 1995 rather than any earlier year is treated as the start of the commercial internet.

1995 connects to:

  • historical years appears in
  • 1998 developed from
  • 1993 developed from
  • 2002 developed from

Hexadecimal

7 × 256 + c × 16 + b × 1 = 1,995

Read as powers of two: 1,024 + 512 + 256 + 128 + 64 + 8 + 2 + 1 = 1,995.

In historical numeral systems

Egyptian

1 lotus, 9 coils of rope, 9 hobbles, 5 strokes

1 × 1,000 + 9 × 100 + 9 × 10 + 5 × 1 = 1,995. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Babylonian

3 corner wedges + 3 vertical wedges (sixties place), 1 corner wedge + 5 vertical wedges (units place)

33 × 60 + 15 = 1995. Places are separated by a space on the tablet, with the higher place written first.

Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.
