Article, Treatise & Programme: N-Grams

Looking at different ways in which information has been conveyed - articles, treatises and programmes - it is clear that programmes, likely in the form of radio and television broadcasts, have become more prominent over time. Notably, this starts in the late 19th Century as technology is beginning to develop. Treatises have gradually diminished, perhaps for reasons of changing vocabulary and reclassification (where this was a prominent term in Medieval writing, the use has clearly diminished and, so far as I am aware, is much rarer nowadays.) Articles, though having apparently diminished, are still in far wider use than the other terms.
