A technology used to make voice and video calls over the Internet. Its not new but from time to time is being developed. Video phone calling was first trialled a few years back over standard phone lines, but these lacked the bandwidth to support stable video calls. Now that more and more homes have moved over to higher-bandwidth broadband services, video calling is now possible in higher quality, and users of services such as MSN Messenger have been able to use webcams to do two-way video for a couple of years now.
Although now 3G technology is available, its kinda costly to talk for long hours. Video calling over the internet is more preferable especially when being far from the one you love. Its impressive how easy our life has been with all the technologies available. Imagine in those days, news spread really slow. Nowadays, within minutes news spread all over the world. You're able to communicate with another person in different time zone. However I find it still not enough because through video calling its still virtual contact with another person. You able to speak and see the person but it will never be the same as physical contact. Furthermore, not everyone like to stay in front of the computer for so long.
p.s. i'm addicted to internet i think i'm alright :P
