The origin of these puzzles was a set of "linguistic equations" such as this one
4J. + 4Q. + 4K. = all the F.C.
which were invented by psychology professor Morgan Worthy and first appeared in a 1975 book of his, under the title "Formula Analysis Term".
Will Shortz then came up with the variant now commonly seen, such as:
29 = D. in F. in a L. Y.
where the left side is an single number and the equation format is no longer really necessary, but is used anyway. These were first published in Games magazine in the May-June 1981 issue under the title "Equation Analysis Test".
Many other people have now created such puzzles, and a British newspaper came up with the alternative name "ditloids". They took this name from a specific one:
1 = D.I.T.L.O.I.D.
which Shortz, however, would have written this way:
1 = D. in the L. of I.D.
The "rec.puzzles archive" site at rec-puzzles.org, where these details can be found, now uses "ditloids".

That's because somebody posted one of these on a puzzles newsgroup:
1 = DITLOID
And somebody finally (after a considerable length of time) came up with the correct answer
One Day In THe LIfe of Ivan Desonavitch (sp?)
which is the title of an obscure Russian novel.
