Sources
107 sources, one line each. Every fact on the site sits next to one of these; this page lists them once.
Wikipedia is used for the settled history, where its articles carry the primary citations. For anything from 2019 on, the source is the paper, the company's own statement, or a named publication, and the Now page says which of those three it is. A row marked unconfirmed there rests on a secondary report.
