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]
The American media critic Douglas Rushkoff was the first to coin the term Viral Marketing in his book ‘Media Virus‘ from 1994. Social media, including Facebook, Twitter and YouTube, play an important role in Viral Marketing. Platforms where information can be shared are particularly suited for this type of marketing. The goal is to spread the marketing message like a viral epidemic. That makes Viral Marketing a relatively cheap way to reach a large audience.
All viral marketing examples — deliberate or accidental — have three things in common: the message, the messenger and the environment. Each part must be leveraged to create a successful viral marketing campaign. Viral marketing campaigns may be created by any size of business and can stand alone or be a part of a larger traditional campaign. The campaigns themselves may utilize a number of tools, such as videos, games, images, email and text messaging, free products, appealing to the emotions of users or viewers, raising awareness to a worthy cause, and making such products, ideas or media easy to consume and share. Viral marketing often relies on the help of an influencer, who has a large network of followers.
The five forces model of analysis was developed by Michael Porter to analyze the competitive environment in which a product or company works. Description: There are five forces that act on any product/ brand/ company: 1. The threat of entry: competitors can enter from any industry, channel, function, form or marketing activity. How best can the company take care of the threat of new entrants? 2

A new venture was started under the wing of Pacific Life Insurance company last year called Swell Investing. They’ve created investment portfolios to cater to the values of certain people. These portfolios contain a number of stocks that fit the theme of the portfolio such as green tech or renewable energy. Dividends received are automatically reinvested to help compound your wealth for now.
Renting out a space room on AirBNB is really easy and their site handles the advertising, payment and feedback system. The process of having your site advertised is quite passive, but having someone in your house has similar risks to real estate investing, that makes it quite hands on. It is worth considering if you are rattling around in a large house, or have a granny-flat that is vacant.
When you write a blog post on your website, that article immediately goes out to your followers. But the content also remains on the website for others to find via search engines or social media. Each time somebody reads your content, there’s the potential to serve them an ad, product for purchase, or affiliate link (many links in this post are affiliate links). Each set of eyeballs that read your content carry the potential for passive income.
If retirement is a goal of yours (and who doesn’t want to retire someday?!?), it’s important to learn how to start investing. In fact, funding your retirement accounts should be at the top of your list. While these accounts won’t help your immediate situation, by stashing cash now, the residual income they create should help propel you through your golden years.
There are three main categories of income: active income, passive income and portfolio income. Passive income has been a relatively loosely used term in recent years. Colloquially, it’s been used to define money being earned regularly with little or no effort on the part of the person receiving it. Popular types of passive income include real estate, peer-to-peer (P2P) lending and dividend stocks. Proponents of earning passive income tend to be boosters of a work-from-home and be-your-own-boss professional lifestyle. The type of earnings people usually associate with this are gains on stocks, interest, retirement pay, lottery winnings, online work and capital gains. 
To ensure that your viral content has the chance to go viral on the top social channels, make sure that the majority of your promotion efforts are executed immediately after the content has been published. This will ensure that you have recency on your side when it comes to algorithms for trending content. From there, you just need engagement with your content on as many platforms possible to help it reach critical mass.
Risk: The tricky part is choosing the right stocks. Graves warns that too many novices jump into the market without thoroughly investigating the company issuing the stock. “You’ve got to investigate each company’s website and be comfortable with their financial statements,” Graves says. “You should spend two to three weeks investigating each company.”
What I Do: I’ve set up multiple investment accounts outside my main operations bank that deals with working capital e.g checking, paying bills. By transferring my money to a couple brokerage accounts and two other banks as soon as it hits my main bank I no longer have temptation to spend on frivolous things. As a result, I can wake up 10 years later and reap the rewards of compounding. My 401(k) is the best example where constant contributions over 18 years has grown to over $500,000 without any savings pain given it just became a part of life. Real estate is also a fantastic asset class for the long term. It’s fantastic to enjoy your home, pay down your mortgage each month, and end up with a paid off asset that has likely appreciated during your time of ownership. 
If you have a brilliant idea that appeals to a specific audience, you could create something like an educational blog or a YouTube tutorial series to generate online traffic. If your content is engaging and it sees enough daily traffic, you could sell ad space on your blog or ad spots on your channel. After you put in the heavy lifting, you can sit back, relax, and enjoy streams of passive income.

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. 

People have a lot of stuff—and they’re always looking for inexpensive ways to store it. What could be easier than having people pay you to store their stuff? Building passive income by offering storage could involve a large-scale investment of buying a storage facility (with cash!) or something simpler like offering your basement or shed. You’ll just need to ensure their items are safe and secure.
A new energy drink company, for example, could create an Internet video featuring a person who consumes the energy drink before performing a seemingly impossible bicycle jump. If the video is made to look real, it may encourage people who see it to share it with others. After the video receives enough views, the company could reveal its true purpose, convincing its viewers to seek out more information about the drink without ever using a traditional advertisement.
4) Treat Passive Income Like A Game. The only real way to begin your multiple passive income journey is when you are making active income. The initial funding has to come from somewhere. Hence, treat passive income as a game that has various levels. If you fail to achieve one level, it’s not the end of the world since you still have active income and can restart. Furthermore, a game is meant to be played with integrity. Using shortcuts (non passive income streams), someone else’s income as a supplement (spouse), or one-offs (capital gains) does not count. The primary purpose of any game is to bring enjoyment to the player and beat the boss.
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.

Speaking of selling stuff online, that's another mostly passive way to generate income. You could generate an income stream for a while by clearing out your basement or attic and selling items on eBay or elsewhere. This can be especially effective with collections. If you have lots of games or jigsaw puzzles that are taking up space and not being used, they can be great sources of income. You might reap a lot by selling new and used clothing you don't need.

Great job, note the home upsizing works only in appreciating housing markets (I’ve done a similar this in CA but it was 7 years same home to gain almost 500k profit which is around the govt cap for tax-free home profits. What a gift! Thanks booming economy and generous govt taxation on home profits). Those proceeds bought our next house cash and invested the remainder in domestic stock (which has been equally profitable).

There is debate on the origination and the popularization of the specific term viral marketing, though some of the earliest uses of the current term are attributed to the Harvard Business School graduate Tim Draper and faculty member Jeffrey Rayport. The term was later popularized by Rayport in the 1996 Fast Company article "The Virus of Marketing",[12] and Tim Draper and Steve Jurvetson of the venture capital firm Draper Fisher Jurvetson in 1997 to describe Hotmail's practice of appending advertising to outgoing mail from their users.[13] An earlier attestation of the term is found in PC User magazine in 1989, but with a somewhat differing meaning.[14][15]
