There’s a second downside to this model. Although I’ve done advertising and sponsorships in the past, and have made hundreds of thousands of dollars doing so, the truth is it takes a lot of time for this business model to start to generate income for you, because you need to build that audience first. In addition, what happens when you build your audience on a platform that ends up changing its algorithm, affecting how often you actually get seen by the audience you’ve built?

Based on my initial experience of passive income, I feel real that real estate is best vehicle to build long-term investment. I live in Los Angeles and was able to cash flow my first rental property. What are you thoughts about starting out to build a passive income portfolio? I have utilized Lendingclub, online savings, and a small dividend/bond portfolio.
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. 
It’s easy to think as passive income as money earned while sitting on a beach sipping mojitos, but there is lots of work involved, says financial coach and retired hedge fund manager Todd Tresidder. If you’re worried about being able to save enough of your earnings to meet your retirement goals, building wealth through passive income is a strategy that might appeal to you.
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.

I love real estate investing, but it requires a lot of upfront capital plus you are going to have to learn to love your tenants (see point 6 below)! Crowdfunded real estate investing gives you a way to still invest in the real estate market, without having to necessarily put in a lot of money upfront. It’s definitely a much more passive investment than owning a flat or a house!
According to a paper by Duncan Watts and colleagues entitled: "Everyone's an influencer",[66] the most common risk in viral marketing is that of the influencer not passing on the message, which can lead to the failure of the viral marketing campaign. A second risk is that the influencer modifies the content of the message. A third risk is that influencers pass on the wrong message. This can result from a misunderstanding or as a deliberate move.
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.
Email campaigns that stand out and bring about a sense of emotion are great to get subscribers sharing with others. Creating calls to actions and valuable content within your email that is timely and closely related to what your subscribers care about will help the virality of your email campaign. In a world where 20% of subscribers open email newsletters it is important to segment your audience to deliver the best content possible and also create clear calls to action so subscribers don’t need to think about what they need to do with your message.
To model Viral Cycle Time’s effect on growth, I searched the web, high and low, looking for a pre-defined formula. To my great surprise, there was no formula that I could find that correctly calculated customer growth, and showed the impact of Viral Cycle Time. What was also surprising, was that I did find several blogs showing formulae for viral growth, but in every case, they appeared to make the same mistake, which was assuming that the entire customer base would continue sending out invitations for every cycle. So I collaborated with my partner, Stan Reiss, who turns out to be a whole lot smarter than I am, and he helped me develop the fomulae that are used in the more sophisticated model for viral growth below:
Messenger: Three specific types of messengers are required to ensure the transformation of an ordinary message into a viral one: market mavens, social hubs, and salespeople. Market mavens are individuals who are continuously 'on the pulse' of things (information specialists); they are usually among the first to get exposed to the message and who transmit it to their immediate social network. Social hubs are people with an exceptionally large number of social connections; they often know hundreds of different people and have the ability to serve as connectors or bridges between different subcultures. Salespeople might be needed who receive the message from the market maven, amplify it by making it more relevant and persuasive, and then transmit it to the social hub for further distribution. Market mavens may not be particularly convincing in transmitting the information.
