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.
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.
Thanks for asking. https://passiveincomemd.com/what-is-passive-income/ gives a good summary of the definition I use. But in brief, it’s income that isn’t proportional to the time you physically put into acquiring it. It doesn’t mean it’s not without work or effort. It’s just that most of the work is done up front and it continues to pay off long after that initial effort. Real estate fits into that box. There’s definitely a spectrum but compared to what we do as doctors, where our compensation is directly linked to our time, most of these things are quite passive.

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.


Wow! What an awesome list! My favorite is the stock photography because I love photography. I have had some success there, particularly with one photo I make some decent income from. I think the key with stock photography is finding a shot that is high demand. Then, find a new unique way to frame that shot. This is the reason my St. Louis Arch photo is a top 10 on both ShutterStock and iStockPhoto. Thanks for the awesome ideas above!
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. 
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).
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. 
In 2013, Oreo jumped on the infamous moment when a power outage caused lights to go out during the Superbowl. In the 34th minute the Superdome experienced a slight blackout which Oreo’s social media team quickly jumped on. Posting a solitary Oreo on a black background with text reading “You can still dunk in the dark” on Twitter and Facebook, it quickly received over 10,000 retweets on Twitter and more than 20,000 likes on Facebook.

Say you sell a boring product that has been seen countless times in homes and on TVs doing its job, like blenders. BlendTec was a company in this situation. Their Will it Blend campaign saw them use their blenders on nearly every Apple product, copies of the latest popular video game, paintballs, and DVDs of Justin Bieber. If you can’t see how that type of content can spread rapidly, you’re in the wrong business.


In order to build an audience, you need to have a platform. You need to have something worth following and sharing; something that’s valuable to others. And that, of course, takes time. That’s not to say you can’t build a huge audience in a short amount of time. But as much as we hear about the people who’ve succeeding at doing this, we don’t hear about the millions of others who are struggling every day to get just a few more fans and followers.
Unlike having to either create something or store a physical inventory of something, selling digital products requires no overhead and no active work to earn money. The blog Paper & Oats put together a great guide on how to get started selling on Etsy. In this guide, they share a few ideas on digital products you can put together and sell in your Etsy store. If you’re someone who’s creative and knows how to design great-looking digital files, this might be a perfect option for you.
Passive income is the Holy Grail for online marketers. It's automatic. Effortless. But, not at first. In the beginning, it's grueling. I liken this to doing the most amount of work for the least initial return. However, over time, as your passive income begins to increase, your reliance on an active income plummets. That's when the real magic starts to happen.

6) Always Remember That Everything Is Relative. The best way to determine worthwhile passive income streams is by comparing the likely return (IRR) with the current risk-free rate of return. If I round up, the 10 year bond yield is at 3%. Any new venture should thoroughly beat 3% otherwise you are wasting your efforts since you can earn 3% doing nothing.

Related to consumers' attitudes toward a brand or even toward the marketing communication, different online and social media statistics, including the number of likes and shares within a social network, can be used. The number of reviews for a certain brand or product and the quality assessed by users are indicators of attitudes. Classical measures of consumer attitude toward the brand can be gathered through surveys of consumers. Behavioral measures are very important because changes in consumers' behavior and buying decisions are what marketers hope to see through viral campaigns. There are numerous indicators that can be used in this context as a function of marketers' objectives. Some of them include the most known online and social media statistics such as number and quality of shares, views, product reviews, and comments. Consumers' brand engagement can be measured through the K-factor, the number of followers, friends, registered users, and time spent on the website. Indicators that are more bottom-line oriented focus on consumers' actions after acknowledging the marketing content, including the number of requests for information, samples, or test-drives. Nevertheless, responses to actual call-to-action messages are important, including the conversion rate. Consumers' behavior is expected to lead to contributions to the bottom line of the company, meaning increase in sales, both in quantity and financial amount. However, when quantifying changes in sales, managers need to consider other factors that could potentially affect sales besides the viral marketing activities. Besides positive effects on sales, the use of viral marketing is expected to bring significant reductions in marketing costs and expenses.[26][27]
