Best Marketing Case Studies

In need of a bit of inspiration!

Maybe I'm wrong but I feel like it's hard to find good case studies and examples of amazing marketing.

And I don't mean funny billboards - I'd love some proper marketing success stories, that include at least parts of the following:

- Objective (E.g Increase revenue/marketshare/awareness by X%)
- Who was targeted and why
- Which messaging and why
- Which channels and why
- Results

I'm unfortunately not exposed to a lot of this broader strategy at my workplace, probably because I'm in a performance marketing role and I'm fairly junior. (Side note: ideally I'd love to transition to a more general marketing role where I might see more of this process, so any advice on this would be amazing too)

Anyway - I'd love to hear any of your best marketing case-studies! Whatever you're proud of from your career, ideally covering some of my points above.

If not, then any good case studies you've read or heard about!

Thanks :)
