Final answer:
The statement that transitioning from PCs to smartphones creates more ad space is false. Mobile screens offer less physical space, which forces advertisers to be more strategic in their approach. Growth in mobile advertising comes from increased usage and targeting potential, not increased ad space.
Step-by-step explanation:
The assertion that users moving from PCs to mobile devices, particularly small-screen smartphones, results in much more ad space is false. Mobile screens are smaller than those of PCs, which limits the amount of space available for advertising. However, what is true is that the growth of mobile device usage has led to an increase in mobile advertising. According to reports by eMarketer.com, mobile advertising has shown significant growth and is projected to surpass traditional forms of advertising like radio, magazines, and newspapers in terms of spending. This is not due to more screen space but rather the increased usage of mobile devices and the potential for advertisers to target users more personally and directly. In the context of the shift towards mobile advertising, marketers have to be more strategic in how they utilize the limited space available on mobile screens to capture the attention of consumers.
