It was the New York Times that came up with the idea: a news alert in your inbox based on a key word of your own choosing (though there were always limits). The service became so popular that the Times started charging for the service.
Leave it to Google: it has perfected the idea with its BETA test of Google News Alerts. There are no limits to word choice. It will send you a news alert based on its monitoring of thousands of news sources (including Mises.org). You can now receive an alert from all news sources in the world that mention the word Mises, for example. No charge.
