“Newsletters began in mid-fifteenth-century Venice. Subscribers would receive handwritten letters twice a week rounding up interesting events. Sixteenth-century merchants used similar news sources to keep track of exchange rates, taxes, and other business news. The form’s popularity expanded in England after the country’s first postal service took off around 1660. This opened the door to news writers, who could use the mail to gather information from distant correspondents and then send the information to readers on a predictable schedule.” – JSTOR Daily
