Final answer:
The correct answer is that TV having the most detailed target audience options is NOT a reason for digital spending outpacing TV spending, as digital platforms typically provide more precise audience targeting.
Step-by-step explanation:
Among the reasons why digital spending now outpaces TV spending, the option 'Because TV has the most detailed target audience options available today' is NOT a reason for this shift. The increase in digital spending is largely due to consumers, particularly younger demographics, spending more time with digital media, the prevalence of mobile devices, and the growing trend of online video consumption. However, TV does not offer the most detailed targeting; digital platforms often allow for more precise audience segmentation.
