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.

In 1999, Daniel Myrick and Eduardo Sanchez began drumming up buzz for their now-legendary movie, The Blair Witch Project, using innovative techniques made possible by the relatively new culture of the Internet. The film is an early example of the “found footage” style that is made to look like amateur video shot by real people. Myrick and Sanchez, along with Artisan Entertainment, capitalized on the realistic look of Blair Witch to build a campaign around it that suggested the footage actually was real.

Sam…just read this article and I want to say that this is the best posting on passive income I have ever read…in a blog, article, or book. Thanks for making a difference and being an inspiration as to how it can all be accomplished. One of the great benefits of the internet is that people are willing to share their stories and experiences with each other online. If we had this when I was working professionally (20-40 years ago), it would have saved me from making some rather poor financial decisions that affected my retirement income. In a way, the internet is making up for the loss of financial security in the loss of The Defined Benefit Plan for retirement. Bravo!

Lending Club is a platform where you can lend your money to other people. You’re the bank. Each note is only $25, so you can invest $1,000 and lend money to 40 people. There are many grades of loan (from safest to riskiest) and investors earn, on average, between 5% and 7% annualized returns.

Marketers aim to spread the word about their brand to a wide audience, and they often do this by trying to make their content go viral. Viral marketing is a technique, which marketers use intentionally to spread their message quickly. Just like a biological virus, a viral marketing campaign spreads from one person to another, resulting in a large number of views, substantial amount of social shares and remarkable brand awareness.
This was a great move for Dove who had become very quiet in the marketplace in the years beforehand. They were able to realign their brand to be all encompassing and to suit young and old women alike. The emotional undertone to the campaign made is hit hard with women no matter what their social standing, religious beliefs, etc. If you plan to carry out a viral marketing campaign similar to this example be careful not to inadvertently distance yourself from certain social groups by appearing too up market or shabby.
If you have a spare bedroom, you can find a roommate or list the space on AirBnB for travelers. Having a roommate is the more passive of the two, as being an Airbnb host will require more work in the form of turning over the room between stays. This is a super painless way to earn $500 to $1,000 a month without much effort – you may even be able to cover your mortgage payment with this extra income!
Many entrepreneurs reading this post will realize that they may not have the means to achieve true viral growth (where they have a Viral Coefficient of greater than 1). Rather than giving up, it is worth considering a hybrid viral model. In the hybrid viral model, you make up for the shortfall in customers by acquiring those through some other means such as paid search, or SEO.
To save time and effort, a person can group two or more of their passive activities into one larger activity, provided they form an "appropriate economic unit." When a taxpayer does this, instead of having to provide material participation in multiple activities, they only have to provide it for the activity as a whole. In addition, if a person includes multiple activities into one group and has to dispose of one of those activities, they’ve only done away with part of a larger activity as opposed to all of a smaller one. 
The fact is, very few people know what goes into making a viral marketing campaign successful until it starts to spread. There are, however, some brands, who have understood what makes the audience tick. In fact, there are some consistent elements in such campaigns, which brands can follow. Let’s take a trip down memory lane and have a look at the top three examples of viral marketing campaigns over the past years. There is a lot you can potentially learn from them as they exactly know how to resonate with the target audiences.
Domain names cannot be replicated. If one is taken, the only recourse would be to approach the owner to discuss a sale. While there are other variations you could choose, sometimes owning a certain domain (especially if it is attached to your business) can be worth the premium. Often, people will scout out domain names that are still available, buy them, and then sit on them in order to sell them down the road. Depending on who may want the domain down the road, you could sell it for a large markup.
On paper, it may seem easy to invest in real estate and earn the rent as passive income, but in a practical sense, it is often difficult to translate this investment into income. Identifying the source which will generate a stable passive income is probably the biggest challenge you might face. You may require external help. Most activities that generate passive income, like starting a blog or selling items on Craigslist or eBay, can end up taking so much time that they aren’t really “passive” activities anymore.
The introduction of social media has caused a change how viral marketing is used and the speed at which information is spread and users interact.[35] This has prompted many companies to use social media as a way to market themselves and their products, with Elsamari Botha and Mignon Reyneke stating that viral messages are "playing an increasingly important role in influencing and shifting public opinion on corporate reputations, brands, and products as well as political parties and public personalities to name but a few."[35]

What I’m doing: I use this site to write out goals like 1) Generating $200,000 a year working 4 hours a day or less, 2) Trying to make winning investments, and 3) Keeping track of my passive income streams with free financial tools. My site and the community helps keep me accountable for progress. It’s important I do what I say, otherwise, what the hell is the point? You should consider starting a site or at least a private journal. Write out your specific goals, tell several close friends and stick to the plan.
If you offered Prismacolor pencils in your online store, you have the option of promoting the GIF through your own social channels in an attempt to get engagement from your own audience using a piece of content that is proven to be viral with general audiences. Depending on the creator of the content, you may be able to upload the content to your channels directly to share or you may need to re-share the content from the creator’s original social post, YouTube channel, website, or other direct link. Your post (or re-share) would include a link to Prismacolor pencils for sale in your online store.
By increasing the exposure of your brand and delivering value to your audience, you have a stronger likelihood of getting the success you need in your viral marketing campaign. Awareness is required even if the content is great so that people can share and make it popular. You need to create something that pulls in the kind of attention that will spread.
If you’re a YouTube personality, this is how you generate your income. An amazing example of this how Antonio Centeno got 1 million YouTube subscribers. If you’re a blogger who gets a lot of traffic to your site and uses advertising or sponsorships, then you’re also following the AA Model. Got a podcast with sponsorships? Same deal. I talk about successful podcast sponsorships and other ways to make money podcasting here:
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]
Your articles are so in-depth and helpful, I’ve never seen anything quite like it. I am a 22-yr old finishing my last semester of college, studying Computer Science and Psychology. I’m in a really good place with my finances (2k savings, no student debt, only expenses essentially rent, groceries, and utilities) and I want to get ahead financially so I can pay my parents back and save up a lot.
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/
Residual income is money that is earned on a recurring basis, typically as the result of a single original action. Rather than earning an hourly wage, residual income is typically generated through an initial investment of time or money with the goal of earning continuous payments. Once the initial investment, product, or service is made, the ongoing income that is earned is generally passive in nature.
If you don’t own another property, though, you can rent out the place you live when you’re not there. For example, many people do this when they live near big events–like conferences or major sports games. They will stay at a friend’s house or even a hotel and rent their place out at a huge markup for the event. Or if you travel routinely for work, you can rent your place out while you’re gone. If you want to learn more, Thrifty Nomads walks you through the entire process of listing and renting your home on Airbnb in this guide.
The disadvantages to consider with viral marketing include the nuisance factor. Due to the large amount of email people receive daily, viral marketing messages may be viewed as spam. Another consideration is negative marketing buzz. A message may not be construed as intended, and could be discussed in a negative manner. Viral marketing can also be hard to measure. 
That’s a nice read! I love your many tangible ways mentioned to make passive income unlike certain people trying to recruit others by mentioning network marketing and trying to get them to join up and sell products like Amway, Avon, Mary Kay, Cutco or 5Linx. People get sucked into wealth and profits and become influenced joiners from the use pressure tactics.

Not everyone is eager to do this, but consider renting out space in your home for extra income. You could take in a full-time boarder, for example, but you needn't be that extreme. Instead, consider renting out an extra room via a service such as airbnb.com or homewaway.com. If you do so for just 20 nights a year and charge $100 per night, that's $2,000 in pre-tax income! If your home is in a desirable spot, maybe you can rent out the whole house for just two weeks in the summer, charging $2,000 per week and collecting $4,000.
But, you don't need to go further than that. You can simply write it and publish it and collect the income. That's all. Send out a couple emails to your list (if you have one) or post it on social media, and there you have it. Passive income. Now, the amount of income you receive depends on the quality of the book you've written. How well did you craft the message? How targeted was the information to your audience? It counts.

Among the first to write about viral marketing on the Internet was the media critic Doug Rushkoff.[16] The assumption is that if such an advertisement reaches a "susceptible" user, that user becomes "infected" (i.e., accepts the idea) and shares the idea with others "infecting them", in the viral analogy's terms. As long as each infected user shares the idea with more than one susceptible user on average (i.e., the basic reproductive rate is greater than one—the standard in epidemiology for qualifying something as an epidemic), the number of infected users grows according to an exponential curve. Of course, the marketing campaign may be successful even if the message spreads more slowly, if this user-to-user sharing is sustained by other forms of marketing communications, such as public relations or advertising.[citation needed]
