In order to watch the live games you must first download one of the free P2P programs that are widely available. Currently there is around eight of these p2p programs available on the net but as with any software i'm sure more will appear in the future. The main eight programs are PPlive, Sopcast, TVU Player, Pcast, PPstream, TVants, PPmate anf TVkoo.
These p2p programs all work in relatively the same way, firstly you install the freeware program onto your computer. Within each program is a channel list, when the channel you want to watch is clicked on it will launch in the player. However as most of these programs are developed in Asia you may find some of the channel lists are in Chinese, Korean, Japenese etc This program can easily be solved by a quick search for the thousands of sites providing live schedules or even links from their sites direct to the football games.
The channels actually originate from people sharing their TV signal, so if you had a TV card installed on your computer you could also share your channels with everyone else. Most of the streaming football or other major sports will have volunteers who will agree to share their TV stations for each and every live match. The more people that then watch these channels at any given time the stronger the signal gets as your computer will act as sort of a repeater, so while you are watching you are actually strenghening the signal for everyone else.
Currently Sopcast and TVU seem to the most popular p2p program to use, probably because they are both Spyware / popup free and thousands of channels can be found from ESPN, Star Sports, Sport Channel 1, 2, 3 and 4, SHTV, Guangdong Sports, the list is endless. According to statistics Sopcast has been downloaded by over 2 million people and hundreds of thousands of people could watch the bigger games. PPlive used to be the most popular but now will only broadcast in China.
The football games that can be found on these channels include all English and European football leagues, Champions League, International football, russian football leagues, Chinese Ultra League, again the list is pretty much endless. Outside of football you can also find live cricket, tennis, boxing, American Football, Ice Hockey and any other popular worlwide sports.
So the arguments for becoming a fan of football over the internet are quite suffient, its free, easy to use, instant and extremely convinient. All you need is a computer, online access and of the course the passion to watch live football on your PC.
