This research examines consumer attitudes towards four SUb-types of interactive digital advertising: internet-based e-and email advertising, and mobile-phone-based SMS- and MMS-type advertising. The differences in attitudes among these four sub-types of interactive digital advertising are also compared. Data are collected from three universities in Taiwan. Data analysis extracts three attitudinal forms (common factors) towards interactive digital advertising, namely, 'informative', 'entertaining' and 'irritating'. Consumer attitudinal forms towards e-advertising and MMS-type m-advertising are both similar and positive (i.e. informative and less irritating and entertaining). Their attitudinal forms towards email advertising and SMS-type in-advertising are less positive (more irritating and less informative and entertaining). Furthermore, the three attitudinal forms towards the four SUb-types of interactive digital advertising are compared. Consumer 'informative' and 'entertaining' attitudinal forms towards e-advertising and MMS-type m-advertising are similar, while their attitudinal forms towards email advertising and SMS-type m-advertising are equal and lower than towards the previous two sub-types of interactive digital advertising. As for the 'irritating' attitudinal form, consumers feel more 'irritated' towards email advertising and SMS-type m-advertising, while their attitudinal forms towards e-advertising and MMS-type m-advertising are equal and less irritated.
