Learning how to use viral marketing in healthcare can be done by looking at some of the best examples from the industry. For instance, the ALS Ice Bucket Challenge raised awareness and funds for amyotrophic lateral sclerosis (ALS) by challenging people to dump a bucket of ice water over their heads or donate to the cause. This campaign went viral in 2014, reaching millions of people and celebrities, and raising over $200 million for ALS research. The Real Cost campaign aimed to prevent youth from smoking by showing the harsh and graphic consequences of tobacco use. It used various media, such as TV, radio, print, online, and social media, to deliver its message to the target audience of 12-17 year olds and has been credited with preventing over 350,000 teens from smoking. The Man Flu campaign promoted a new product called Man Flu, a natural remedy for the common cold, by poking fun at the stereotype of men exaggerating their symptoms when they are sick. This campaign used a humorous video, a website, and a social media campaign to generate buzz and interest for the product, achieving over 10 million views, 100,000 shares, and 50,000 comments.
