The purpose of this paper is to understand the behavior of simultaneous use of two forms of media. It seeks to analyze the characteristics of people who engage in such behavior and the factors regulating it. This analysis should provide a foundation for a comprehensive understanding of the influence of the new medium of internet on the existing medium of television. The principle source of data for this study was a time use survey. According to this survey, 12.6% of home internet users made simultaneous use of both television and computer internet in the space of their home. The average daily length of time spent in such simultaneous behavior was 10.2 minutes. The main factor correlating with such simultaneous use was length of television viewing : when heavy television viewers also made use of the internet, there was a high likelihood that they would use the internet simultaneously with television. The proportion of people who used mobile internet simultaneously with television was 16.2%, and the average daily time spent this way was 8.2 minutes. Simultaneous use of mobile internet and television was greater among women, and tended also to be greater among younger people and heavy television users.
