Organizing Patterns and Evolution of Indian Movie Industry

In this study we focus on basic structural and temporal characteristics of a network formed by linking movie actors in accordance with their co-occurrences with other fellow movie actors. In an actor network, the actors are represented as nodes and a link is formed between a pair of actor if they appear in the same movie. Each link is assigned a weight, representing the number of co-occurrences of the pair in different movies. A statistical analysis of the structure of networks reveals the organizing pattern of movie actors and temporal analysis of networks shows the evolution of the movie actors and industry on a whole. In this study we compare the national and regional movie industry in India along selected weighted network measures. The data set contains movies (from 1980 to 2013) encompassing three movie industries, namely Bollywood (national), Tamil and Malayalam (regional). We observe strong agreement between the three movie industries for degree distribution, strength distribution, average weight as a function of degree, and weighted clustering coefficient as a function of degree. The aforementioned observance does not deviate in temporal scale. However we observe a key difference in affinity measure between national and regional movie industries suggesting more acceptance of new actors in case of regional movie industry.
