Back in the days, TVs became the hub of the house. These days, each family member usually carry their own mini-hubs in the form of smartphones and tablets. Trying to reclaim their territory, TV makers have made TVs smarter so that they could do anything their owners want. Including shopping, at least for digital goods. To that end, LG has announced its partnership with Paymentwall to bring the ability to make online purchases on a host of its Smart TVs, powered by its custom webOS 3.0 platform.
