Ads: Apple's next billion dollar empire

I doubt it. They have a better opportunities by continuing to advance their other service offerings.

Finance and health are mammoth areas that they can still mine for profits. A few years ago I would have agreed but they have actively walked away from the ad business and have gained users because of it. They would be mad to get back to selling ads when they have other possibilities.

They are one of the few companies that can change the 2 fields because of their size, resources, and the societal penetration of the iPhone. If I were Tim Cook and was given the choice between ads and Health, I would choose Health 100% of the time. Apple can earn a ton of money while doing some good. You can't say the same thing with the ad business.
