Right now Apple's Services Business consists of:

  - Apple Music
  - iCloud
  - App Store / iTunes / Apple Books
  - Apple Pay
  - Apple Care
  - Licensing (i.e. default Google search)
  - Apple News+

Coming later in the year:

  - Apple Arcade
  - Apple TV+
  - Apple Card

I'm expecting Apple Arcade to be a huge source of revenue which I'm eagerly awaiting for myself (and my kids) to get off the cesspool of scammy Dark UX IAP land mines that currently proliferates the App Store.
