This investment bank presentation helps explain the complicated digital marketing industry for normal people

The digital marketing industry is a multi-billion dollar space. And it's a complicated one too - even people who work in the sector struggle to get their heads around the latest acronyms and trends.

Investment bank LUMA Partners famously created the LUMAScape which shows the myriad middle-men technology companies that sit between a marketer choosing to spend money on an online ad, and that ad reaching the consumer.

Now LUMA Partners has created a new presentation that aims to demystify the digital marketing landscape - and it's particularly useful for those who aren't immersed the industry.

LUMA Partners has kindly allowed us to publish the presentation and commentary, which covers topics including the huge amount of M&A activity in space, the limited number of ad tech and marketing tech IPOs, and the newest digital marketing trends.
