The military and certain universities use a connection of networks in order to exchange information. This inter-networking is now what we have come to know as the Internet. Thanks to Internet service providers, this technological phenomenon was brought straight to our homes. Now, we do an array of activities using the Internet, and most of them have become so intertwined with our daily lives that it's already quite difficult to live without them. The Internet has become a multi-billion dollar industry and a lot of people have become millionaires and billionaires from it.



Chatting

Humans are a naturally social species. We always had the need to communicate and you'll see this through ancient texts, cave paintings by early man, and the development of the telecommunications industry. This is why there are so many websites that offer chat room services. A very popular application has been with instant messaging. People have been using this service to chat with friends, family, and even for business purposes. Some companies even use conference chat on instant messengers for some of their meetings.

Online auction

Some people buy, some people sell, some do both. It's at auction website where people can purchase hard to find items from other users. What's great about it is that you can also sell things at these websites as well. There are people that make a lot of money from merely selling items on those sites.

Peer to peer services

People simply love music and ever since peer-to-peer services have been introduced, music has been all around us more than ever. Although these have gone though a legal battle, as record companies and other artists would say that it violates copyright laws. Nowadays, most of the music you can get from the Net has to be paid for (although there are some artists that give out songs or even entire albums for free).

Video streaming

A number of websites now offer video streaming services where users can upload their own videos for public display. A lot of users of these sites have become household names because of the videos they post. A number of entertainment companies saw the potential of these websites, and decided to join the bandwagon themselves. They would create their own user profiles, and release new videos from their artists exclusively on those websites. This has been a great marketing strategy for them.

Online shopping

Shopping has become a whole new experience since online stores have arrived. With online shopping, you no longer have to bust it out at busy malls during Christmas, and you simply have to just move around your mouse and click away. The only downside to it is that you don't see the physical item before buying it, but buying things through online stores has made it extremely convenient for most occasions. Let's say you are in California, and you've been dying to purchase an item, but it's only found in London. All you have to do is to type in the name of that item on a search engine, and you will see what online stores have them available and at what price.
