I signed up for the advert free premium tier. Still get adverts for content. Went to play NBC Nightly news, shows a segment from the weekend. :( Didn't dive deep into other content offerings but looks good at quick glance. Here is a link if you have trouble installing the app:

Update:

Here is a positive review from Gizmodo. They say there are some old but very popular series that are worth watching like Law and Order, parks and rec, etc... I never watched those.
