You probably already own a computer or a smart phone. Do you know how easy it is to connect these to your TV?
You can get all the catch up services and premium services like NowTV and Netflix on your phone or computer and you probably only need a cheap cable to connect them to your TV.
Take a look at your computer and see if you have a HDMI port on there, if you do just find an old HDMI wire, plug in it to the computer, then the TV, put the telly on the HDMI channel and boom, it should work just fine. Then you can watch all the catchup telly you like. This is great as it allows you to use an adblocker too.
Phones can be a bit trickier. Android phones are easiest to use for this. But you will want to google it to make sure you get the right cable from our list below.
