 Shortly after the cancellation of the series, the staff of the  marketing department of the NBC TV network confronted the network  executives and berated them for canceling Star Trek, the most  profitable show on the network in terms of demographic profiling of  the ratings. They explained that although the show was never higher  than #52 in the general ratings, its audience profile had the  largest concentration of viewers of ages 16 to 39, the most sought  after television audience for advertisers to reach. In other words,  the show, despite the low ratings, had the precise audience  advertisers hungered for, which was more than ample justification to  consider the show a big success.
