Final answer:
The 10th category of social media could include consumer review sites like Yelp or TripAdvisor, which are platforms where users can share reviews and photos, influencing public perception and business reputations.
Step-by-step explanation:
The 10th category of social media could refer to various types of platforms depending on how you categorize them. As described by Investopedia's Maya Dollarhide and Amy Drury, several types exist: social networking, bookmarking, social news, media sharing, microblogging, and online forum sites.
However, considering these types, one that could be considered the 10th could include consumer review sites like Yelp or TripAdvisor, which blend social interaction with business and service reviews.
These platforms enable users to post reviews and photos of their experiences with products, services, and establishments, which in turn influences public perception and can significantly affect the reputation and success of businesses. They embody a social aspect by allowing users to discuss and share opinions, creating a community around shared interests and experiences.
Hence, consumer review sites demonstrate another way through which digital media shape friendships and connections, as well as how they can affect businesses and services.
