Here in the UK most of the big television channels have their own websites. Following the incredible success of
BBC iPlayer many of them have chosen to follow suit and offer shows as free streams you can watch in your browser. BBC iPlayer basically offers a variety of BBC shows from the last seven days as free streams. The technology works well, it works in any browser, and the quality is reasonably good. It is also completely advert free.
Channel 4 offer a service called 4OD, and they actually made whole series of some of their most popular shows available. You can watch several episodes of things like Father Ted for completely free via your browser. Unfortunately on 4OD there are adverts but far less than you would find on traditional broadcast television. ITV and Channel 5 have belatedly followed suit with their own websites offering a range of repeated shows as free streams.
This is definitely the easiest way to watch TV on your PC as it requires no equipment or software. However you are limited to the selection available on the websites, and the shows only appear there after they have aired on scheduled broadcast TV.
