N-grams data

The Corpus of Contemporary American English (COCA) is the most widely-used corpus in the world. In March 2020 it was updated for the last time (with data up through Dec 2019), and the n-grams data from the corpus was updated in April 2020. The following are the major changes and improvements in the n-grams data.
 

Feature	Previous	COCA 2020
Corpus: size	400 million words	More than twice as large, at one billion words
Corpus: how up to date	Texts from 1990 - ~2012	The most recent texts are from Dec 2019. There are 20 million words each year from 1990-2019 (+ about 240 million words from blogs and other websites from 2013). So there are about 600 million new words of data since the previous data was released in 2012.
Corpus: genres	Spoken, fiction, magazine, newspaper, academic.	Same five genres as before (with about 120-130 million words per genre), plus the three new genres: -- Blog posts and other web pages (120-130 million words for each of these two genres). So much of what we consume nowadays comes from the web, and these genres include many words that don't occur much elsewhere (e.g. ebook, webpage, browsing, password, template, meme, snarky, off-topic, downloadable, open-source, updated, (to) monetize, upgrade, debunk, archive, pirate, upgrade). -- TV and movies subtitles (130 million words). This is by far the most informal language we've ever had in COCA. Many studies (e.g. A, B, and C show that the data from subtitles agrees with native speaker intuitions about their language even better than the data from actual everyday conversation (like in the BNC). Until now, COCA didn't really have this highly informal language.
N-grams data	Users had to purchase separate data for words and wordID+lexicon formats.	All three formats (two "words" formats and the wordID+lexicon format) are now available for the same price as one single format (previously).
