CONVERGENCE
Literally, coming to a point with time. The values in the sequence 1, 1/2, 1/3, 1/4,... converge to zero whereas the values in the sequence 0/1, 1/2, 2/3, 3/4, ... converge to one. Convergence requires that the differences between neighboring values decrease. If they do not, they may tend to infinity as in 1, 2, 3,... or end up oscillating as in ... +1, -1, +1, -1,... The convergence model of communication postulates that as people communicate with each other they become more similar in knowledge and in attitudes and thus converge to form a homogeneous distribution. (Krippendorff)
