Apple tv

The free year is 'Apple TV+' - this is a streaming channel containing only series made by Apple: at the moment there isn't a large selection but it will increase.

Other services such as iTunes or Netflix are paid for either on a subscription or pay-per-view method and are not part of the Apple TV+ free year.

Anything not part of 'Apple TV+', the subscription service, has to be paid for either as a subscription, as with Netflix, or on a pay per view basis as on iTunes. There are a few apps offering free movies but these are mostly very old B-movies and often in appalling quality so unless that's a specific interest of yours they aren't worth bothering with.

As stated the Apple TV + service contains Apple original content. Currently there are 10 series and 2 movies. Content is regularly added. The subscription does not entitle you to content from the iTunes store, which is 3rd party and done through purchase or rental.
