Here are a few of my take-aways from the first 40 slides:

  • There are now 3.8 billion internet users (51% of global population)
  • E-commerce is growing quickly but still "only" 15% of retail sales in USA (this surprised me)
  • Wow. Ad spend on mobile went from 0.5% in 2010 to 33% in 2018 (!)
 

Ad spend on mobile went from 0.5% in 2010 to 33% in 2018

Doesn't really surprise me. Outside of the tech world a lot of people only have smartphones and tablets. If you're not mobile optimized by now, well better way late than never, but damn.
