You brought some awesome examples. One of the best ways to get your campaign off the ground is by starting with the ideal audience. I find that I can use data to find my top customers and then make those into ambassadors, nurture those relationships, to create an epic viral campaign.

The list of passive income ideas could go on forever. As you search for the best fit, keep an eye out for ideas that show positive long-term track records. Do other people make money on the idea? Has it come back to bite someone who tried it? Some people ask me about passive income options like drink, vending, or other rental machines in public places. The bottom line? Don’t fall for any passive income ideas that promise a quick return or require huge amounts of money upfront. They will sabotage your other financial goals. Look for ideas that are steady, profitable, and trustworthy. Do your research. And never go into debt!
Instagram, also owned by Facebook, may use similar algorithms to determine the types of trending content appearing in a user’s news feed or Explore tab in the Instagram app. Smaller businesses appear to have a better ability to trend on Instagram using viral content compared to Facebook, although publishers and individuals may begin to take the lead there as well.

While stocks are terrific income producers, they can be volatile. Every few years, the stock market tends to stagnate or drop for a while before recovering, and that can be problematic if you were counting on your stocks having a certain value at a certain time.

Viral advertising is personal and, while coming from an identified sponsor, it does not mean businesses pay for its distribution.[6] Most of the well-known viral ads circulating online are ads paid by a sponsor company, launched either on their own platform (company webpage or social media profile) or on social media websites such as YouTube.[7] Consumers receive the page link from a social media network or copy the entire ad from a website and pass it along through e-mail or posting it on a blog, webpage or social media profile. Viral marketing may take the form of video clips, interactive Flash games, advergames, ebooks, brandable software, images, text messages, email messages, or web pages. The most commonly utilized transmission vehicles for viral messages include: pass-along based, incentive based, trendy based, and undercover based. However, the creative nature of viral marketing enables an "endless amount of potential forms and vehicles the messages can utilize for transmission", including mobile devices.[8]
