Here is a rudimentary definition of share of wallet:
Money spent on a product divided by a total amount spent in that product category
Let's say that a person consumes media with the following channels:
- AM/FM Radio (free)
- Satellite radio $16.99/mo - $21.99/mo via SiriusXM
- Podcast subscriptions ($4-5.49/podcast/month)
- Audio books subscription $7.95-$14.95/mo via Audible
- Television (basic broadcast channels are mostly free with ads)
- Satellite TV - DIRECTV ($64.99–$154.99/mo), DISH ($79.99–$109.99/mo)
- Amazon Prime Video (14.99/mo or $139/yr)
- Print newspaper, $520/yr NY Times (full experience, daily print Mo-Su); sad, LA Times does not have this service for my zip code; local newspaper daily digital + print Sunday ($25/mo); the other local newspaper $21-26/mo daily digital + print Sunday
- Print magazine, avg $20/magazine/year (excluding luxury magazines)
The affluent consumer likely subscribes to more than one content service and probably spends more than $500/year on the media-as-entertainment category. Amazon Prime Video's wallet share of the above scenario is 27.8%. It's really hard for other streaming services to compete with Amazon's business model, since Prime Video is a feature of Amazon's Prime service not its core reason for existing. Everyone else is just a one-trick pony.
Consumers are subscribed to multiple services. The average US consumer subscribes to 12 paid subscriptions spread across videos, music, gaming, news, food delivery, and other entertainment. Netflix raising its prices shouldn't be that big of an issue. Is it?
