Use Tellybean, it allows for video conferencing calls.

Not possible.  It's not like a PC or Android device where you can upload software to it.

You'll need an internet source, either connect via WiFi or CAT5 cable directly into the Ethernet Port.  If you have a cable provider hook an HDMI to your box.  Turn it on and it will run you through a set up.  The LG content tab/app will let you download things like Netflix, HBO, YouTube, etc. Hope this helps some.

That television is so old I doubt LG will send you out any updates for aps.  

No sorry.  Just saw the other query and had an answer for that.  I would consider using a USB  device to get online content such as AMAZON Fire TV or ROKU stick.

Skype, the Microsoft-owned video calling service, has quietly announced that it will no longer offer an app for smart TVs starting in June. ... Skype's smart TV app will no longer receive updates after June 1, but those who have already downloaded it can continue to use it.Mar 8, 2016

sorry, but Skype is no longer supported by smart TVs

Hit the button that looks like a house and look in the LG store. 

Be frustrated like the rest of us

It would be nice if they could add a browser that could use the features of websites such as the History channel.

Is the Hallmark app available in the LG app store?  I've never seen it.
