For a couple of years now, Apple has been exploring subscriptions as a way of bolster revenue in the face of slowing iPhone growth. This year saw a turning point in that strategy, with Apple TV+, Apple News+ and Apple Arcade joining the company's suite of subscription services that already included Apple Music, AppleCare, and iCloud.

But as this is a relatively new frontier for the company (at least in terms of emphasis), Apple is still testing the waters of different approaches. The latest of these is the introduction of a discounted annual subscription to Apple Arcade priced at $49.99, about a $10 savings compared to the $4.99 monthly subscription that was introduced in September.
