Sources claim that the new way of interacting with advertisements is being tested, alongside Instagram's now "Shop Now" feature:
"It has even run tests with restaurants to sell menu items right from the Instagram feed, without the need to click off the app’s main feed, said an ad agency source familiar with the test.
Some of the shopping tests incorporate features like Apple’s force touch screen feature, which lets consumers apply pressures in their clicks to switch among multiple product options in the images, the source said."
Introduced to the market almost 2 months ago, 3D Touch hasn't shown its full potential on iOS just yet. However once developers find a bearing, apps focused on shopping and other activities are expected to become more interactive.
