But it's false that companies that don't have a consumer product don't draw intense interest. Ask Enron. Or WorldCom. Or Blackwater. Or Lehman Brothers. Or the folks behind the AOL and Time Warner merger
I would like to think the blood test product scandal was interesting on its own merits, amongst all of the other frauds going on in this country, but I don't think it really was elevated to the collective conscious because of that.

It was elevated because of the massive PR push by Theranos itself. I never even heard of Theranos until they did a massive PR push in 2013 or 2014. That, combined with the fact the company is valued at $9 billion, apparently has no actual working product and numerious other interesting facts about the company including it's well-connected-to-Gov (and large) [former?] Board of Directors, co-founder who committed suicide, at least two-large corporate partnerships that blew up (Safeway, Walgreens), etc., etc.
