If you are wondering how to get tv channels on your pc, there are few ways
to achieve that. However, the solutions range in terms of channels offered
and quality of video and audio service. There are free and paid methods.

Free methods to get tv channels on your pc:
You can visits television streaming sites like WWITV and ChannelChooser
that allows you to watch some channels for free. There are many channel
selections grouped by function for you to choose from. However, as of every
kind of free service, there are drawbacks. Firstly, the video playback is
not smooth and it stops from time to time. This is because many people are
accessing the websites at the same times since it is a free service. These
traffic use up the bandwidth of the server and hence causes the performance
degradation. This limitation also affects the video quality.
Paid methods to get tv channels on your pc:
You can purchase a PCTV card which can be installed into your PC
(internal) or plugged into the USB port (external). The device is then
connected to the broadband connection to enable your PC or laptop stream
live television. Typically, a device like that gives you access of 200 to
300 channels and cost a few hundred dollars.
You can also go for satellite tv software which when installed on your PC
or laptop, enables you to watch thousands of live satellite television
channels through the use of broadband connection. Whether you use a PCTV
card or satellite tv software, you only pay a one-time fee and can
subsequently watch live tv as long as you want. No monthly subscription and
no pay per view fees. However, the satellite tv software is my personal
recommendation as no hardware is needed and a good software will cost no
more than $50.
