Video search platform Blinkx floated on London’s AIM index today and immediately pulled of a 90s-style surge, rising 40 percent from the opening of 45p to close at 63p. Blinkx plc was effectively created last month when Autonomy spun off its consumer division and merged it with Blinkx. The flotation for the combined entity raised £25 ($50) million and was due to value the company at £125 ($247) million, but the surge (reaching 67.5p) saw it reach £180 ($355) million.

Perhaps remarkably, few of the big players have yet got in to the video content search space yet so, whilst one might ordinarily expect a start-up to seek exit via acquisition by one of the Big Three, Blinkx - headquartered in London and San Francisco - clearly believes it still has plenty of time to make its supposed advantage count.
