I got the offer and I took it. I have a Chromecast, it's an excellent device.For those YouTube TV Subscribers since June of 2018 (I am not, only since 2019, but my buddy sent me this:
For the rest of December, Google is giving loyal YouTube TV subscribers a free Chromecast with Google TV (normally $49). The catch? You will need to have subscribed to YouTube TV
since June 2018 with no pauses or cancellations to qualify for the complimentary Chromecast.
Google is notifying eligible customers through their YouTube TV account’s email address, so check your inboxes if you’re part of that dedicated crowd. The offer is only valid until December 31, which gives you just a few weeks to claim the free Chromecast before the deal is over.
