I wasn’t thinking so much of plagiarism as I was about the simple act of someone sharing and passing it along to someone else. With e-Books, for instance, although I know there are several formats for them, I assume they are mostly PDFs to download. I don’t think it’s possible to password protect a PDF for opening (I think you can do it for printing or editing), nor to have some kind of time limit on being able to open it. As for courses, how do you ensure that the link or file doesn’t get passed around and accessed for free by people who didn’t pay?

In 1994, Tobin launched a beta version of PC Flowers & Gifts on the Internet in cooperation with IBM, who owned half of Prodigy.[10] By 1995 PC Flowers & Gifts had launched a commercial version of the website and had 2,600 affiliate marketing partners on the World Wide Web. Tobin applied for a patent on tracking and affiliate marketing on January 22, 1996, and was issued U.S. Patent number 6,141,666 on Oct 31, 2000. Tobin also received Japanese Patent number 4021941 on Oct 5, 2007, and U.S. Patent number 7,505,913 on Mar 17, 2009, for affiliate marketing and tracking.[11] In July 1998 PC Flowers and Gifts merged with Fingerhut and Federated Department Stores.[12]
Nice One, I would like to add another (and very important tip, for my opinion) idea for a passive income. Annuities. you can create yourself a Lifetime Incom Plan. it’s like a privet pensions if you do it the right way. you need to find one that is safe and affordable because lots of them are NOT GOOD (to say the least). the good ones will give you a guaranteed income for life.

As someone who's been immersed in a number of online industries for quite some time, I know a thing or two about what it takes to succeed in this arena. However, just like you, I started at ground zero with little knowledge, but a great deal of passion. What I learned along the way were some invaluable lessons from failure that hurt at the time, but helped immensely in the grand scheme of things.
