A quick look at the table that shows the effect of varying the Viral Cycle Time shows that customer growth is dramatically affected by a shorter cycle time. For example, after 20 days with a cycle time of two days, you will have 20,470 users, but if you halved that cycle time to one day, you would have over 20 million users! It is logical that it would be better to have more cycles occur, but it is less obvious just how much better. A quick look at the formula tells the whole story. The Viral Coefficient K is raised to the power of t/ct, so reducing ct has a far more powerful effect than increasing K.
Definition: Unique Selling Proposition or USP is the one feature or the perceived benefit of a good which makes it unique from the rest of the competing brands in the market. It is that very reason which motivates a buyer to purchase that product even though it might be costlier than other products. Description: Unique Selling Proposition or USP is a very important concept used during the time when a company promotes its product through its advertisements in both TV as well as print media which eventually attracts a consumer to buy a particular product. The key to boost the sales of the product effectively through advertising is to highlight the USP of the product prominently. Unless you highlight the USP, consumers will not be tempted to buy your product. Every product should have its own USP, which makes it stand apart from other products in the similar category. USP is different for different products. Let’s take an example of a restaurant which is very famous across the world for its quick Subway Sandwiches. The company makes the sandwiches healthier for consumers. Consumers who are looking for a quick meal can walk into any subway outlet and get a quick sandwich made, which contains nutritional value. In this way the company is able to create its own niche market across town in India. The USP of the product is a nutritious sandwich at an affordable price. USP is a very important component in developing the product. A strong unique selling proposition makes you stand apart and also plays an important role in branding your product. But, USP alone can guarantee to a product’s success. Superior product quality and at par service, both before and after-sale are very important in creating the foundations of a market for a product. Always remember, with a distinct USP, the company doesn’t even have to bother about competition because if you have developed something which has not been developed by others, then you are the only player or a market leader in that specific product category (Example – iPpod by Apple).
Venture Debt – I invested $120,000 in my business school friend’s venture debt fund. He started his own after spending 8 years at one of the largest venture debt funds as a Managing Partner. I’m very focused on income generating assets in this low interest rate environment. The true returns are yet to be seen, as the fund has a 5-7 year life before it returns all its capital.
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.
Since then, P2P lending has exploded onto the scene. More companies like Prosper and Lending Club have jumped on the P2P bandwagon, and investors are beginning to realize it’s an excellent source of passive income. As an investor, you fund an account and loan small amounts (like $25) to a variety of borrowers across a broad set of risk levels, creating a diverse portfolio.

This is the best post I’ve seen on passive income streams. I’m similar to you in that I worked in IBanking for a few years but wanted out. My approach is a little different, instead of starting with the CD’s, I’m trying to build up my net worth with riskier asset classes such as stocks and real estate to get the benefit of compounding. Then, as I approach my retirement year goal, I’ll start moving them into CD and bond ladders. In theory at least, it’s best to have the highest net worth just before retirement, then convert them to risk free passive income. You’re method is more patient and probably more practical than mine. I guess I’m willing to take more risks.

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.
When money is lent to a partnership or S-corporation acting as a pass-through entity (essentially a business that is designed to reduce the effects of double taxation) by that entity’s owner, the interest income on that loan to the portfolio income can qualify as passive income. As the IRS language reads: "Certain self-charged interest income or deductions may be treated as passive activity gross income or passive activity deductions if the loan proceeds are used in a passive activity."
The term Marketing comes from the words ‘market’ and ‘getting’; conquering the market. The term marketing has been around for over a 100 years. Today, it’s still about large companies wanting to conquer the market, gain market share and (new) customers. Marketing methods are comprehensive and Viral Marketing is a relatively new way. This technique increases the awareness and reach of a product or brand by using social media. It’s word-of-mouth advertising using the internet. The more people who know about it, the better. Each company that uses a marketing communication goal to express a specific marketing message can do so by publishing digital video clips, for instance. These days, commercial organisations employ viral marketing to generate brand recognition, launch a new product or draw attention.
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.

When a taxpayer records a loss on a passive activity, only passive activity profits can have their deductions offset instead of the income as a whole. It would be considered prudent for a person to ensure all the passive activities were classified that way so they can make the most of the tax deduction. These deductions are allocated for the next tax year and are applied in a reasonable manner that takes into account the next year's earnings or losses.

In the case of viral marketing, "viral" refers to something that spreads quickly and widely across its audience. Viral marketing is a deliberate enterprise, though the distribution of a message happens organically. As such, social media provides the perfect ecosystem for viral marketing, though it has its roots in traditional word-of-mouth marketing. While the practice was much more widely used in the early to mid-2000s, as new internet businesses were being created in extreme numbers, it is still common among internet-based business-to-consumer (B-to-C) companies. The widespread adoption of social networks, including YouTube, Twitter, Instagram, Snapchat and Facebook, has enabled modern viral marketing efforts and increased their efficacy. 
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!

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.

The campaign didn’t target Dove’s products but instead focused on changing a woman’s perception of how she sees herself, also changing the way how Dove is viewed as a company. It is said that “Woman aged between 18-34 are twice as likely to think highly of a brand that made an empowering ad and nearly 80% more likely to like, share, comment, and subscribe after watching one.” Through the video, Dove wanted to make women realize that they are overly-critical of themselves to make them feel better about their appearance.

It isn’t easy to create a YouTube channel that is popular. If you’re not a funny person, don’t try to upload wacky videos – it won’t work. But you might find traction uploading quality how-to guides in your field. Because there is so much traffic, no field is too small. Creating videos on YouTube is also a really good way to add quality to your blog or website.

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]
