Rational Review News Digest commenced publication on December 23rd 2002, and has appeared every non-holiday weekday since then (except for a one-week scheduled vacation in 2008).
Its true history, however, goes all the way back to 1991, when Libernet, the freedom movement's first daily news and commentary "roundup," commenced email publication. In the late 1990s, the first major libertarian "portal" site, Free-Market.Net, began publishing another "roundup" called Freedom News Daily, which later acquired/absorbed Libernet.
On the evening of Thursday, December 19th, 2002, the board of Free-Market.Net's owner entity, the Henry Hazlitt Foundation, voted to declare bankruptcy. The Free-Marke.Net web site -- and with it, publication of Freedom News Daily, shut down literally overnight.
At that point, several Freedom News Daily staff members, who also published a webzine (Rational Review) of their own, came together to ensure that the freedom movement would continue to be served by a daily web- and email-based news and commentary "roundup." The newsletter debuted the following Monday.
In 2003, the assets of Free-Market.Net were acquired by the International Society for Individual Liberty, which resumed publication of Freedom News Daily. In late 2004, ISIL and RRND partnered to continue publication of FND as a "re-branded" edition of RRND.
