Ask HN: Is entertainment getting the Google Chat treatment?

Today I received an email from Google informing me that "Play Movies & TV is moving to Google TV" and was curious about when the announcement was made, so I went Googling for it and instead found this:

https://support.google.com/googleplay/thread/102498448?hl=en

So, there used to be Play Movies & TV, which was an offshoot of Google Play, and now it's become YouTube, but it's also become Google TV, but Google TV used to be the Android-based OS that ran on some smart TVs, but those TVs now need to use YouTube for the same functionality?

Is Google benefiting from naming churn somehow? It doesn't seem to have helped them with chat, but now they're trying it for their entertainment stuff? Why?
