As the question stats How many people make enough Internet marketing to support themselves or their families.
Well I don't for sure on a good month I make $300-600. I have other sources of income that supply's me with enough to survive tho.
Eh, I'm about halfway there - making around $900 net per month right now. If I can double that, I may quit my full time job and pursue IM hardcore.
I am just a part time, because its my interest . At night, I am a IM'er, in morning I am a student. I sleep for only 3-5 hours.
Depends what you mean by IM, being an online entrepreneur isn't IM. IM is simply traffic arbitrage (which is hard). There's a lot of people who have internet based companies or leverage the internet to gain new business. I have well over 100 friends on facebook who make a living online some of them are doing over $1m a month online.
It depends and differs from people to people. Many of us are earning a lot with online jobs. Some of them are doing as profession and some are doing as side income.
