Earning From Internet

Is it real ? is it truly we can work and got earning from internet ? Thats the most questions in my mind and maybe some of us. As we know internet is one kind way to connect to the other around the world.
The positive site is, our communications nowadays is unlimited,everytime you want to. Sending news, files, movies, songs and it possible to make phone call with cheap price via internet and it called VOIP, and so muich positive things we can do with internet. Negative sides are, so many crime online, like creditcard hijacking, virus sphreading, controlling other systems to do something bad.

I just wanna talk about business on internet, maybe some of us still confuse and not sure about that, but maybe some article could be your refferences. And from my point of view it is very possible. Just thing like this, if on tv we watch some commercialsbreak that offering products, and than we ordered it by phone, just like that how it works. But not all of internet business is right, there is many bad person that use internet to do their crime, so be carefull, watch and learn carefully every online business you want to do.
Maybe i can pick Google adsense for an example, it have prooved by several people that succed to manage their business with $ 12.000/ month earning. You can search the fact by searching it on google ( search engine ). And i thing that business still work and maybe still good business field in next days, cause people doesnt need to move from their home. Just sit and type a thing on computer that connect to internet. They just need 3 hours per day to work with huges earnings.
You can believed or not, but be wised, that now is millenium age, so dont be missed. The fact that anything getting easy and easier.
Your question for me maybe is do i have earn from internet ? my answer truthly not yet but my friend did. Even he`s not get the cash but he got pin from google adsense, so i`m interested to prooved it. I know i`m still new and maybe some of you, but there is always the first right ? so i`m try to do my best to realized that, wish me luck guys and all the best wish for all of you.
