Getting businesses to advertise on your podcast, either at the beginning or end or both is a great way to create a revenue through podcasts. Most businesses won’t be keen to advertise on your podcast until you can prove a large number of listeners. Therefore, it is unlikely you will be able to start out from the get-go with sponsors. But once you accumulate regular listeners or a high number of downloads from iTunes, you can start to sell advertising space on your podcasts.
I also noticed that in your passive income chart at the bottom that you don’t include your internet income other than sales from your book. Is there a reason for that? Do you not consider is passive because you are actively blogging all the time to create it? Or do you just not want readers to know how much money you generate from blogging activities?
In January 2018, I missed my chance of raising the rent on my new incoming tenants because it didn't come to mind until very late in the interview process. I didn't write about my previous tenant's sudden decision to move out in December 2017 after 1.5 years, because they provided a relatively seamless transition by introducing their longtime friends to replace them. I didn't miss a month of rent and didn't have to do any marketing, so I felt I'd just keep the rent the same.
According to Uncle Sam, you need to be "materially involved" in an enterprise to earn active income. With passive income, it's just the opposite, as the IRS deems you to be earning passive income if you're not materially involved with a profit-making enterprise. By and large, expect income to be taxable if you are engaged in a passive income enterprise. You will need to report earnings to the IRS.
It will take a long time to build up your photography skills when you start, but it can be a great job for stay-at-home moms if you choose your genre carefully.  For example, if you shoot weddings you’ll have to work every weekend, which means goodbye family time.  You wouldn’t have chosen to by a stay-at-home mom if you were willing to not be with your family.  But there are other genres that work great for moms, like doing real estate pictures for Realtors, doing baby photography, senior pictures, etc.  I wrote more about the myths of being a professional photographer here.
29. Videos – This could be an entire section on it’s own. Many people have made money by creating YouTube videos. Evan of EvanTube is a kid and he has made millions by creating reviews of products that other kids his age would use. It’s not easy to get views into the millions, but once you do, you’ll start seeing some cash come in. Many bloggers have completely turned to videos to get their point across by starting a video blog.
Even if your car rarely goes unused long enough to rent it out to a visiting driver, you can still potentially “rent it out” by turning your vehicle into a rolling advertisement. The site pairs car owners with advertisers who are looking for mobile billboards. Drivers can earn up to $400 per month by agreeing to have their vehicle wrapped with a vinyl decal (called a car wrap) provided by an advertiser. Generally, your program will last anywhere from 6 to 24 months, and you get paid for following your normal driving routine.

If I have a blog that is getting 100,000 page views a month that means that I’m probably getting at least 50,000 people to the site (most blogs will do between 1.2 to 1.4 pages per session). That means I have to try and get some small percentage of those people to buy something from me if I really want to do well. If I can’t get them to buy something then (in some cases) I have ads running on the site that will make me money anyways.

However, there are ways for stay-at-home moms and dads to earn a bit of extra cash to supplement the family budget without leaving the house or sacrificing time with the kids. In fact, here are 10 money-making opportunities that can be pursued when your children are at school or asleep, or possibly even when they are awake and demanding your attention. The earnings potential is modest, and not every opportunity will be right for you, but over the course of a year you could pocket hundreds – and possibly even thousands – of dollars.
Mike, I don’t consider the income from FS to be passive, as I’m spending time commenting to you right now. But since 75% of my traffic comes from search, the most traffic I would probably lose is 25% for probably a year. And then my search word rankings would probably slowly fade given frequency of posting new content is one of the search algo variables.

However, if you're looking for realistic ways you can start earning money online now, then it really truly does boil down to seven paths you can take towards profit. Some will provide you with immediate results, helping you to address your basic monthly necessities such as rent, utilities and groceries, while others have the potential to transform your life by revolutionizing your finances in the long term.
