Blinkx accusations raises concerns over online adverts Blinkx, a spin-out from Mike Lynch's Autonomy, acts as a search engine to help viewers find entertaining videos, then sells adverts around them. As of September last year, Mr Lynch was Blinkx's fourth biggest shareholders, with a 4.49pc stake. Blinkx, which was spun out of Autonomy and floated on Aim in 2007 and claims to be based on technology "conceived at Cambridge University," fell more than 90p to a low of 85p as the traders digested the report, wiping more than £350m off the company's market value. The controversy has raised questions over how companies like Blinkx generate revenue. Neil Campling, analyst at Aviate Global, told the Financial Times: "Part of the problem the industry has is that it is often difficult to get clean, tangible metrics of page views and click-through rates. There are layers of complexity [to these businesses] which, combined with a high valuation multiple, makes for a volatile stock.
