The U.K.-based Autonomy has exercised an option to take over the consumer site Blinkx. The site had about $10-12 million invested in it since it was founded in 2003. With the takeover, Autonomy has spun off its consumer division (the technology), merging it with Blinkx Inc (the video search site), renaming the two together as Blinkx, plc, and then will float them through an IPO on London’s AIM market in May. Autonomy plans to hold 10% of the demerged unit after the listing. The move should also help Autonomy focus on its enterprise division.
