Big data is at least four different problems (2015) [video]

Can anyone recommend any articles/blogs/etc on big data success stories outside of ad tech and retail web tech? And I mean big, business defining successes.

It's not to say they don't exist, obviously analytics is super important, but after being involved in it for 10+ years, it is rare that I have seen any game changing results come from big data analytics teams. Lots of small incremental improvements, sure, but I wonder about the ROI given the infra costs.

Interesting he brings up zynga and their impressive petabytes worth of clicks. They weren't able to sustain a business off of that insight so was that a technology failure or a business model failure.

Paraphrased from description:

- Large amounts of source data

- Large amount of processing/analytics of data (ML and other models)

- Large flow of data (data per time unit)

- Diverse input sources (combining data from different sources and formats)

Obviously these aren't mutually exclusive.
