Google just updated its search capabilities on iOS to make it easier to look for media content—like movies and music—online. When you do a Google search on a specific song, TV show, or movie. The results will show in the Knowledge Panel icons for services that offer the content, like iTunes, Google Play, Spotify, YouTube, etc. If you click on these links, it’ll take you straight to that app or service. And if you haven’t signed up for the specific service, pricing information will be displayed, too. This feature should show up on both Google Search app as well as on mobile web browser.
