As computers get faster and bandwidth increases more and more information can travel over cable or DSL lines or by satellite much faster. You can watch streaming movies on demand on sites like netflix.com or blockbuster.com. For smaller movies and tv shows online you can just go to youtube.com and do a search. Even Amazon has pay per view now with streaming video. Not all of your favorite television shows will be available there however. Sometimes you need to set up a log in account with the network that produces the show in order to watch it. You can also get pirated shows using an outlaw service such as torrent or limewire, but it is not recommended and you can get some seriously damaging viruses on your computer. It is not worth the risk and you should avoid these open file sharing sites.
On Demand services are routinely offered free by most cable providers and satellite television companies including Comcast and Astound. Not all programs are available however and even free television networks like NBC charge a small fee to watch your favorite shows. In comparison you will not get as good an image watching tv shows online but you will save money. Again, not all shows are available online.
If you are traveling to a foreign country you may not be able to download or watch your favorite tv shows online by going to the network sites. Pirating is so prevalent in many countries that networks and studios do not allow streaming video to go out on their broadband.
TV shows online can also mean sports programming and there are several sites where you have to pay a fee like a season pass in order to watch your favorite sports teams. This can be great if you are Los Angeles Lakers fan, for example, and you are travelling all the time but still want to see their games every day. Special NFL, NBA, NHL and MLB packages are available for those specific sports tv shows online. They are not cheap however so be prepared to pay up or else miss a lot of games. This is just not acceptable to truly devoted fans and most will pay whatever it takes to watch their games on a consistent basis.
If you dont want to miss your favorite programs you dont have to anymore, not with tv shows online and other on demand packages available. You can also just record the shows and watch them later on our TIVO. Whichever method that you choose everyone agrees that it is always good to have options.
