The Monitor began publishing on Dec. 3, 1975, the result of a merger between the County Line Courier and the Queen's County Telecaster and Commentator. When it started to publish, the Monitor printed Charlottetown news, television listings, and a variety of feature columns. Column topics included highway safety, hairdressing, Island personalities, sports, live entertainment in Charlottetown, alcoholism, personal opinion, and political commentary. The amount of news published in the Monitor declined throughout its publication history. Later issues often featured a theme, such as baseball, gardening, or Old Home Week. The paper apparently ceased publication on August 10, 1977.
