The later versions dropped certain symbols and introduced other simplifications to earlier versions. Pitman 2000 (1975–present) introduced some simplifications and drastically reduced the list of abbreviations to reduce the memory load, officially reduced to a list of 144 short forms. Pitman New Era (1922–1975) had the most developed set of rules and abbreviation lists. Additional modifications and rules were added to successive versions. The original Pitman's shorthand had an "alphabet" of consonants, which was later modified. There have been several versions of Pitman's shorthand since 1837. For example, the sound "R" has two kinds of strokes: round, or straight-line, depending on whether there is a vowel sound before or after the R. Another method of vowel indication is to choose from among a selection of different strokes for the same consonant. This is often enough to distinguish words with similar consonant patterns. However, to increase writing speed, rules of "vowel indication" exist whereby the consonant stroke is raised, kept on the line, or lowered to match whether the first vowel of the word is written at the beginning, middle, or end of a consonant stroke-without actually writing the vowel. Each vowel, whether indicated by a dot for a short vowel or by a dash for a longer, more drawn-out vowel, has its own position relative to its adjacent stroke (beginning, middle, or end) to indicate different vowel sounds in an unambiguous system. Vowels are drawn before the stroke (or over a horizontal stroke) if the vowel is pronounced before the consonant, and after the stroke (or under a horizontal stroke) if pronounced after the consonant. The predominant way of indicating vowels is to use light or heavy dots, dashes, or other special marks drawn close to the consonant. Pitman shorthand uses straight strokes and quarter-circle strokes, in various orientations, to represent consonant sounds. Doing this requires a writing instrument responsive to the user's drawing pressure: specialist fountain pens (with fine, flexible nibs) were originally used, but pencils are now more commonly used. One characteristic feature of Pitman shorthand is that unvoiced and voiced pairs of sounds (such as /p/ and /b/ or /t/ and /d/) are represented by strokes which differ only in thickness the thin stroke representing "light" sounds such as /p/ and /t/ the thick stroke representing "heavy" sounds such as /b/ and /d/. Pitman shorthand was the most popular shorthand system used in the United Kingdom and the second most popular in the United States.

The shorthand was converted into words during the trip back to Chicago, where typesetters and telegraphers awaited them. The practice got national attention in 1858 during the Lincoln–Douglas Debates which were recorded phonographically.

It was first used by newspapers who sent phonographers to cover important speeches, usually stating (as a claim of accuracy) that they had done so. Shorthand was referred to as phonography in the 19th century. Like most systems of shorthand, it is a phonetic system the symbols do not represent letters, but rather sounds, and words are, for the most part, written as they are spoken. Pitman shorthand is a system of shorthand for the English language developed by Englishman Sir Isaac Pitman (1813–1897), who first presented it in 1837.
