A flood of new fans into fandom. This is sometimes connected with a resurgence of interest in science fiction in general. The activity of the Triumvirs in the Second Transition brought in the first of these rushes; many of its elements, like Harry Warner, Jr.., remained and became actifans.
In the 1960's, the "Star Trek" TV series brought an even larger influx of new fans into fandom, and still larger infusions into fandom occurred in the '70's and '80's because of the many "sci-fi" television shows and movies of the era. Older fans who came into fandom through interest in written science fiction generally consider these infusions of visual media-oriented people to be a continuing Barbarian Invasion. Fortunately, fandom is flexible enough to accommodate a wide spectrum of interests. So it sez here.

|With the increase in the number of prozines, and the swing of emphasis back to them in the Second Transition, a flood of new fans came into fandom, usually thru the Triumvirs' activities, and many remained and became actifans. Harry Warner and Jim Avery were the forerunners of these, appearing in the middle of 1938. The invasion strengthened the reaction toward the pros, and eventually shifted the center of fan population westward to near the census center of population, in the Mid-East.
