YouTube Kids has proven to be a popular way for parents to give their children access to a limited collection of YouTube content, even if that collection occasionally includes videos depicting suicide and cannibalism (oops!). The service has slowly been expanding its global reach, and now Google has added 11 more nations to the availability list.
Google is doing its darnedest to make developers happy. To a certain extent, anyway - it still makes some major mistakes on a pretty regular basis, but at least it's trying to expand availability for paid apps to more users and, crucially, more developers. Today developers in Azerbaijan, Iceland, Peru, And Yemen can submit paid apps to the Google Play Store, as well as offer in-app purchases. Previously Android users in all four nations could buy apps, but not sell them.
Nothing stopped developers in these territories from publishing apps before, but Google had no way to pay them, so they were limited to free downloads.
