There's a new Startup Battlefield Disrupt Cup winner, Amazon Prime Video hits Fire TV and Oath and Mozilla escalate their legal spat. It's The Daily Crunch for December 6, 2017.

1. TechCrunch Disrupt Battlefield winner is Lia Diagnostics

The winner of TechCrunch's Startup Battlefield at Disrupt Berlin this year is Lia Diagnostics. It's a company that created a new at-home pregnancy test that you can safely flush down the toilet.

The startup's approach combines material science with CPG innovation to deliver a product truly tailored for women with convenience and privacy in mind. If you read this newsletter regularly you know I featured them previously – but I have no influence on who wins Battlefield, it just seemed like the best competitor in the field.

2. Amazon Prime finally arrives on Apple TV

After a lot of promises and a lot of waiting, Amazon Prime Video is now on Apple TV via a brand new app. It's a great way to access the streaming original shows Amazon makes, as well as a broad selection of film and TV content.

3. Oath and Mozilla trade lawsuits

Our parent company Oath is suing Firefox maker Mozilla for alleged 'breach of contract' regarding Firefox's switch from Yahoo to Google as its default search engine. Guess what, Oath overlords – that ship sailed a long time ago.

4. HQ Trivia on its way to Android

HQ Trivia, the mobile trivia game sensation, is currently only available for iOS, but that's changing soon. HQ put a teaser image out for the Android version of its app, with strong indication that it's coming before year's end.

5. Microsoft is putting full Windows 10 on ARM

Microsoft wants to put Windows 10 on lower-powered hardware, including ARM devices. This isn't like Windows on the Surface RT, however – it's a full-fledged version of the OS with access to all the same applications and software.

6. Google removes YouTube from Echo Show... again

Google had allowed Amazon to restore YouTube to its Amazon Echo Show devices briefly, but that respite is over. YouTube is being pulled once again, and now Google is also pulling it from Fire TV, due to a growing feud between the two companies. In the end, consumers lose.

7. Mashable to lay off 50 and shut down Asia office after Ziff Davis sale

Mashable is going to lay off 50 employees following the close of its sale to Ziff Davis, which is being described as a fire sale with a total deal value of less than $50 million. One person who won't lose their job: Mashable founder Pete Cashmore, who will reportedly stay on at Ziff Davis post-acquisition.
