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.
Passive income is earnings derived from a rental property, limited partnership or other enterprise in which a person is not actively involved. As with active income, passive income is usually taxable. However, it is often treated differently by the Internal Revenue Service (IRS). Portfolio income is considered passive income by some analysts, so dividends and interest would therefore be considered passive.

Oreo did in fact have 15 person strong social media team standing by to jump on anything that could have happened during the evening but you can still be this viral with a one person team if you can keep on top of current trends in your industry. Learn from this example of great viral marketing and use current events to position your product in the middle of it in a positive light.

It was easier recouping the lost $60,000 in rental-property income than I expected. For so long, my primary mindset for passive income was rental income. Having $815,000 less mortgage debt but still generating roughly the same amount of passive income with a much larger cash balance feels great. Further, my passive-income portfolio got even more passive, which is good as a stay-at-home dad to a newborn.
But that didn’t stop Rovio from switching up their strategy. They decided to build a fanbase in smaller European markets. Three months later, Angry Birds hit the top spot in the Finnish app store after only a few hundred downloads. And from Finland, it snowballed to hit number one across Sweden, Greece, and Denmark. In the process, the app gained 40,000 downloads.

Viral marketing is more about reaching out and touching the passion point of your consumer so that the passion drives the message and the message continues to reach the masses without assistance from you. You can orchestrate a viral campaign, but very seldom are viral campaigns that are orchestrated as successful as those that are just driven by the passion of a consumer. For it to reach a level of success your consumer must feel they have a personal stake and investment in the success of your campaign.
The campaign became successful and viral with over 17 million people participating in the challenge worldwide. Many celebrities including Bill Gates, George W. Bush, Oprah Winfrey, Tom Cruise, Mark Zuckerberg, Rihanna, Tim Cook, Rafael Nadal, and Cristiano Ronaldo took part in the challenge. Below video shows the Ice Bucket Challenge taken by Bill Gates:
Another way to wring income out of stocks, even if they don't pay dividends, is to buy stocks that you expect will appreciate in value over time and then, when you need income, sell some shares. If you have a fat portfolio of such stocks when you retire, you might sell some shares every year to create a cash stream for yourself. Studying and choosing the stocks that will perform very well for you is easier said than done, though, so if you don't have the interest, skills, or time to become your own stock analyst, consider simply investing in a low-fee broad-market index fund or two, such as one based on the S&P 500. Here's how much you might accumulate over several periods if your investments average 8% average annual growth:

Many content creators, or people who simply upload a random video, have found themselves become famous almost overnight. It’s not about the resources and budget — it’s all about what catches the attention of the internet. Marketers don’t always need a large-scale production with a celebrity to make their campaign funny, surprising, relatable, or informational. 
​I’ve been into home décor lately and I had to turn to Etsy to find exactly what I wanted. I ended up purchasing digital files of the artwork I wanted printed out! The seller had made a bunch of wall art, digitized, and listed it on Etsy for instant download. There are other popular digital files on Etsy as well such as monthly planners. If you’re into graphic design this could be an amazing passive income idea for you.
You can find dividend stocks using Google Finance Stock Screener which is free to use. Set the search criteria for the P/E Ratio, and Dividend yield (shown as a percentage) criteria.

At age 55, I own high-end rental properties (near the beach) and commercial buildings servicing the medical industry. I was widely criticized during my career for not living up to my income; that is, buying big homes with many fancy cars. I married a great woman who understood that saving and investing today meant a better lifestyle and more freedom tomorrow. Our passive income is half of my active income from sales, but my net worth has increased substantially. We are both happier and healthier than we were in the high-stress pressure cooker of franchise sales. The naysayers have become converts to the concept of passive income, but they have locked themselves into a “big hat, no cattle” lifestyle. It has been a great ride!
Depending on the product(s) you sell, you may have to get more specific to find the most viral content most appealing to your target customer base. The fastest way to do some topic-specific viral content research is using hashtags or keyword searches on each respective network. Instagram, for example, will give you the top posts for the specific Instagram hashtags, followed by the most recent posts.YouTube orders keyword search results by relevance, then by popularity. Verified YouTube channels will typically lead the pack if they have any applicable videos.Twitter sorts keyword and hashtag search results by relevance and popularity, with posts from verified Twitter users leading the pack.These searches and similar on other top networks will show you what people see on each network when they search for keywords or hashtags related to the products your business sells. If you can create viral content for those networks, you stand a good chance at coming up in searches made by your target customers. As you analyze the trending content, be sure to note specific details, such as the following.
Network marketers have long understood the power of these human networks, both the strong networks as well as the weaker networked relationships. People on the Internet develop networks of relationships, too. They collect email addresses and favorite website URLs. Affiliate programs exploit such networks, as do permission email lists. Learn to place your message into existing communications between people, and you rapidly multiply its dispersion.
Viral marketing is a continual, interactive process. A company that implements a viral compaign shouldn't simply let it run its course without adjustment. The Blair Witch campaign remained active on Internet message boards, interacting with real fans and regularly updating websites with more information based on fan discussions. It, like most viral campaigns, succeeded because it grew along with the interest in the product.
​Udemy is an online platform that lets its user take video courses on a wide array of subjects. Instead of being a consumer on Udemy you can instead be a producer, create your own video course, and allow users to purchase it. This is a fantastic option if you are highly knowledgeable in a specific subject matter. This can also be a great way to turn traditional tutoring into a passive income stream!
Viral content doesn’t just generate traffic from the top social networks. It can give you a leg up in SERPs – Search Engine Results Pages. In Google search results, for example, if you can’t rank for a high-competition keyword, you may be able to get your product featured in content from a publisher that can do so through Google News. Google News’ algorithm focuses on the content’s diversity, freshness, textual relevance to the search, and originality.

Viral marketing or viral advertising is a business strategy that uses existing social networks to promote a product. Its name refers to how consumers spread information about a product with other people in their social networks, much in the same way that a virus spreads from one person to another.[1] It can be delivered by word of mouth or enhanced by the network effects of the Internet and mobile networks.[2]
