A rumor spreads through a population rapidly, at a rate that depends on two factors: The more people who have heard the rumor, the more rapidly it spreads, and also the more people who have not heard the rumor, the more rapidly it spreads. These two factors make the logistic model a good one to study the spread of rumors. And, clearly, there is a maximum value for the number of people hearing the rumor: the entire population.
