In order to develop the definition of media multitasking(MM), the researcher defined MM as
engaging in multiple media activities simultaneously, including multiple windows on a single
media platform and/or multiple media. In the context of Uses & Gratification research, the
researcher studied the relationship motivations of consumers with MM behavior. This paper
suggested two kinds of motivation list; functional motivations(information, entertainment,
habit, and social communications) and motivations for specific media(TV, newspaper/
magazine, internet, and mobile phone).
Using survey data collected in Korea and USA, this study found that all kinds of functional
motivations have influence on MM in Korea, but entertainment and habitual motivations are
more powerful on MM in USA. Finally, through the discriminant analysis, motivation of
mobile phone was verified as the most important variable in MM including all countries. But
also, the researcher found simultaneously detailed different phenomenon by cross cultural
circumstances. So, the implications of these findings are discussed.
