Amazon is smaller than Verizon Media in this space. Microsoft and Verizon Media are not independent - Microsoft handles Verizon's search ads, Verizon handles ads on other Microsoft properties: https://about.ads.microsoft.com/en-us/solutions/ad-products/...
That said, single market players like TheTradeDesk or Xandr are larger in their own markets than verizon media, but probably not compared to the combined publisher and advertiser business: https://www.atlantic.net/vps-hosting/top-10-dsp-providers/
Ah interesting. Yeah, I’m not sure how a full proper ranking or comparison for digital ad market would be done. There’s lot of ad networks including the DSP list. Ad spend perhaps? Most of the major sites or apps that are only for their own property don’t include outside ads. I’m thinking LinkedIn, Pinterest, Snap, Twitter, Reddit, Yelp.
I’m not certain on all of this though. Chumbox ads (Taboola, etc) have proliferated to a whole range of sites including top ones by now too.
But then IAC, Verizon Media’s biggest properties, would be a mix of different things.
