Support for the HBO NOW streaming service started rolling out to the Google Assistant, as suggested by the newly updated official support pages for the Google Home smart speaker. The functionality itself allows you to tell your digital companion to cast HBO NOW content on a compatible Chromecast device and already supports Netflix, CBS All Access, and CWTV. While HBO partnered with Google to integrate its video streaming service into the tech giant's growing artificial intelligence ecosystem, HBO GO still isn't part of the voice-enabled casting package. However, if you have neither, getting HBO NOW should be significantly cheaper than obtaining its counterpart seeing how HBO GO is technically a free service that's only available to consumers paying for an HBO subscription through a licensed cable provider.
If you're paying for HBO NOW, you'll have to link your account to your Google Home through its dedicated mobile app. To do so, access the main Settings page of the Google Home Android app by tapping the hamburger menu icon in the top-right corner, select the "More Settings" option, and find the "Videos and Photos" section on the following menu. From there, you simply have to tap link next to the HBO NOW option which should automatically appear on the list if you have its dedicated Android app installed on your device. The final step is as simple as entering your HBO NOW login information in the Google Home app.
With the newly added support for HBO NOW, HGTV is the only remaining service that has yet to become compatible with the Google Assistant and was announced as one of the platform's upcoming partners at the latest iteration of Google I/O this spring. The Mountain View, California-based tech giant has been pursuing partnerships with many video content platforms in recent times with the goal of expanding the capabilities of its smart speaker and AI companion and additionally grow its ecosystem. More similar casting features are likely to be debuted by Google in the near future, especially as the firm continues its IoT push with the newly released Google Home Mini and the upcoming Google Home Max.
