Adware Controversy[edit]

A lengthy criticism of blinkx by Harvard Business School Associate Professor[44] Ben Edelman, published in January 2014,[45] sought to prove that blinkx continued the adware operations of two companies it acquired, Prime Visibility Media Group[46] and Zango,[47] and was defrauding advertisers. Blinkx responded point-by-point in March 2014, stating that it did not install adware without user consent and it they did not wholly acquire Zango or its assets.[48] An earlier, 2009 blog post by Ken Smith, Zango co-founder and former CTO, supported Edelman's assertion that blinkx acquired all of Zango's assets.[49]

Forbes contributor Peter Cohan claimed that Edelman's post caused a massive drop in blinkx's stock price,[50] and further noted that blinkx's initial, now-deleted corporate response on 30 January 2014[51] was largely an attack on Edelman's methods, rather than on the content of his analysis. However, New York Times blogger Mark Scott theorized that Edelman's undisclosed client(s), who funded his research on blinkx, may have been hedge funds who profited from shorting the drop in blinkx's stock price.[52]

Endelman published further research in April 2014, claiming that blinkx offered users deceptive software installers and used deceptive pop-up advertisements.[53] He continued to defend his claim that blinkx purchased all of Zango's assets, including its physical headquarters, and argued that an FTC order against Zango in 2007[54] may still apply to blinkx. A section of the post co-authored with digital fraud investigation consultant Wesley Brandi also defended and furthered his initial claims that blinkx was defrauding its advertising affiliates.[55]
