Nice sleuthing by Rohin Dhar at Priceonomics:

As we were researching the economics of the SkyMall business model, a darker story emerged. SkyMall recently merged with a newly formed company called Xhibit Corp, a company that trumpets itself as a “cloud” marketing software company, but in reality makes its money from dubious sources. With even a small amount of research, this company, Xhibit, raises all sort of red flags.

Interesting background on how SkyMall makes money and how they’ve ended up where they are today
