Final answer:
WW's partnership with Oprah Winfrey exemplifies the use of an influential social media user, or influencer, to promote a brand's visibility and impact consumer behavior. Influencers can quickly spread information and awareness to their large audiences, making them valuable marketing partners.
Step-by-step explanation:
By partnering with Oprah Winfrey, WW (formerly known as Weight Watchers) was demonstrating the power of working with a highly influential type of social media user known as an influencer. Influencers like Oprah can reach and engage with vast audiences through their online platforms, wielding the power to rapidly spread awareness and inspire action amongst their followers. This marketing strategy leverages the influencer’s credibility and established audience to promote a product or service, thus enhancing brand visibility and potentially driving consumer behavior.
In contrast to ambassadors who may have a formal partnership with a company, influencers often have a less formal relationship but possess significant social impact due to their large followings. Their endorsement can lead to quick dissemination of information and can be particularly effective in the early stages of promoting a cause or a brand.
