Final answer:
The false statement among the options provided is that most social media does not have a direct media cost (option D). While creating accounts might be free, the use of social media for business usually involves both direct and indirect costs.
Step-by-step explanation:
The question asks which statement is not true about social media and businesses. Among the given options, the not true statement is option D: 'Most social media does not have a direct media cost.' Although it's true that creating a social media account on platforms like FB may not incur a direct cost, effectively leveraging social media for business purposes often involves advertising and promotional expenses that do have direct costs associated with them. Moreover, the time and resources spent on managing social media can also be considered as indirect costs. Therefore, while the initial presence might be free, the overall use of social media for business can involve significant costs.
Now let's look at the other options: A) is true because regularly updating social media is crucial for engagement; B) is true as social media operates on a one-to-many communication model, and C) is true since many firms engage with customers through social media; E) is also true because one of the advantages of social media is the ability to respond quickly to current events.
Hence, the answer is option D.
