Thanks for the great article…although I have to point out many of the items listed are not passive but active, such as selling bodily fluids, writing blogs or resumes, and collecting bottles and cans. To be truly passive, the income source must require no effort on your part (after initial setup). Real estate, dividends, P2P lending…these are truly passive income sources.
The ALS Ice Bucket Challenge began four years ago and was created to raise awareness for the debilitating disease. For the challenge, you had to pour ice cold water over your entire body and then nominate a friend to do the same. This became a movement that raised $115 million in the summer of 2014 alone. Because ... who doesn’t want to watch a family member or friend pour freezing cold water on their head?
Another way to generate passive income is to invest and be a silent partner in a business. This is very risky, but with risk comes the potential for high returns. For example, several years ago both Lyft and Uber were looking for private investors to invest in their companies. Today, they are worth billions - but you as an investor would only reap that benefit if they go public via an IPO, or get acquired. So, it's risky.

The solution was to create a video entitled “The Princess Machine.” In it, three bored girls build and launch a Rube Goldberg machine designed to do one task but in the most complicated way. It shows engineering skills and GoldieBlox toys, physics and chain reactions. It could be straight out of a Dr. Seuss book. And somehow it entrances the viewer for the full two minutes.

Using influencers in viral marketing provides companies several benefits. It enables companies to spend little time and budget on their marketing communication and brand awareness promotion.[47] For example, Alberto Zanot, in the 2006 FIFA Football World Cup, shared Zinedine Zidane's headbutt against Italy and engaged more than 1.5 million viewers in less than the very first hour. Secondly, it enhances the credibility of messages.[48][49][50][51][52] These trust-based relationships grab the audience's attention, create customers' demand, increase sales and loyalty, or simply drive customers' attitude and behavior.[50][51] In the case of Coke, Millennials changed their mind about the product, from parents' drink to the beverage for teens.[53] It built up Millennials' social needs by 'sharing a Coke' with their friends. This created a deep connection with Gen Y, dramatically increased sales (+11% compared with last year) and market share (+1.6%).[53]
I wouldn't think of a high yield savings account as a source of passive income but your savings should be getting something (less like Seinfeld syndication residuals and more like a commercial jingle residuals!). It won't make you rich but it's nice if your baseline, risk-free rate of return on cash is 1% or more. The best high yield savings accounts (or money market accounts) offer higher interest rate and there is absolutely no risk. CIT Bank currently leads the pack with the highest interest rate.
Whereas Kaplan, Haenlein and others reduce the role of marketers to crafting the initial viral message and seeding it, futurist and sales and marketing analyst Marc Feldman, who conducted IMT Strategies' viral marketing study in 2001,[citation needed] carves a different role for marketers which pushes the 'art' of viral marketing much closer to 'science'.[23]

Refinancing your mortgage is a passive income generator? Yup, it sure can be. If you're making monthly mortgage payments of $1,600 now, and you can reduce that to $1,300 per month by refinancing your home loan at a lower interest rate, you'll keep $300 in your pocket each month. Of course, refinancing isn't free -- there are closing costs. Still, if you plan to stay in your home long enough to more than break even, refinancing is well worth it. As an example, if your closing costs are $6,000 and you're saving $300 per month, you'll break even in 20 months -- less than two years!
In 2014, ad agency Ogilvy & Mather Paris set up wifi hotspots in areas of Paris that did not have wifi connections. But to use these special hotspots, you had to select the Scrabble network, create your best word, and earn free wifi minutes based on your score. Like regular Scrabble, players could earn more points with longer words. And if you shared your words on Facebook, you got to double your score (and thus your wifi minutes).
I have only dabbled in drop-shipping before when I had an eCommerce platform 6 years ago or so. I think it is something that you could do on the side, but you would want to do in depth research on the industry you want to get into before setting up shop. It may be a little less passive up front, but over time you could take your hands off the wheel.

We respectfully disagree. While you can't guarantee a piece of content will go viral, you can certainly build in viral characteristics that dramatically improve your odds. At Viral Shot, we have created numerous pieces of content for clients that have gained significant traction, generated thousands of leads and helped spread brand awareness. We do have a fairly simple formula that works very well.
When I started building my architecture-related business in 2008, I made my first dollar through advertising. I’d spent a lot of time and money building the site and getting traffic. Then one day I threw an ad on the site one day, and I made $1.18. Sure, I could find that much under my couch cushions—but that’s not the point! The point is that I was able to build something online, put an ad up, and make money without having to do anything. I learned it was possible, and it motivated me to move forward.
Writing an e-book is very popular among bloggers, as many have noted that “it's just a bunch of blog posts put together!” You will not only have to make an investment of time and energy to create the e-book, but market it correctly. However, if marketed correctly (through blogging affiliates in your niche, for example), you could have residual sales that last a very long time.

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. Gilles de Clerck, founder of the Growth Revolution, talks about it here - https://sharesomefriends.com/blog/referral-marketing/


To clarify and organize the information related to potential measures of viral campaigns, the key measurement possibilities should be considered in relation to the objectives formulated for the viral campaign. In this sense, some of the key cognitive outcomes of viral marketing activities can include measures such as the number of views, clicks, and hits for specific content, as well as the number of shares in social media, such as likes on Facebook or retweets on Twitter, which demonstrate that consumers processed the information received through the marketing message. Measures such as the number of reviews for a product or the number of members for a campaign webpage quantify the number of individuals who have acknowledged the information provided by marketers. Besides statistics that are related to online traffic, surveys can assess the degree of product or brand knowledge, though this type of measurement is more complicated and requires more resources.[24][25]
