In 1967, the first fanzine "Spockanalia" was published, in New York City. These fanzines, then newsletters, would continue to grow in publication, throughout the 1970s. The very first convention was held at the Public Library in Newark, New Jersey in 1969, with about 300 in attendance. 1972 would mark the official beginning of the major conventions, and the first true one would take place in New York City, on January 21st - 23rd. It was named: "The International Star Trek Convention"; 300-500 fans were expected, and over 3000 showed-up. It was organized by super-fans Joan Winston, and Betty Jo Trimble. The second successful large-scale convention, was held in Detroit, later that same year.

Both the "Committee" (for conventions), and "Welcommittee" ("STW" - a fanzine & newsletter directory) were formed, upon the success of the NYC '72 convention. Many of these members were also directly tied-in, with the various popular fanzines, and later, full-fledged commercial products. In 1973, "The West Coast Star Trek Convention" would bring-in over 10,000, in Los Angeles. Trekkies / Trekkers continued to draw headlines, and all the original series cast, rode the convention publicity wagon, too. "The International Star Trek Convention" in 1976, attendance peaked, within the range of 20,000 - 50,000 (due to being oversold with counterfeit tickets), with thousands being turned away.

By the time of the original T.V. series 10th run in 1972, it could be easily stated that "Star Trek" had become, an nationwide re-run phenomenon (also marked the end of paying residuals to the series cast). The series finally found the audience numbers, when in syndication; particularly, with the after-school crowd. It was simply all gravy, from that point onwards for Paramount Pictures; the original series was turning-in some serious profits (by the mid-70s, worldwide). Series creator Gene Roddenberry, was able to resurrect "Star Trek", in the form of an animated series by 1973; however, short-lived (22 episodes). The fan demand, and activity would ultimately, help bring back the original cast; in a 46-million dollar feature film. The conventions of the 70's, were key in publicly demonstrating; the seriousness of fans insatiable quest, for all things "Star Trek".
