Many of the companies in this space have used their technology for other applications and now see an opportunity to repurpose it for the advertising market. Digitalsmiths, for example, was using its audio and image recognition to index TV shows so networks and stations could locate clips for promos. Wizzard Media is a voice-recognition company that has worked with corporations such as IBM and AT&T but now hopes to apply its speech-to-text technology to contextual podcast advertising. The market also includes YuMe Networks, which discerns a video's content to sort it into vertical categories; ScanScout and Adap.tv, which hope to place contextual ads along the bottom of videos to complement pre- and post-roll advertising; and PodZinger, which uses audio-recognition technology to allow consumers to search for podcasts and advertisers place relevant ads within them. ------------------------------ Digitalsmiths http://www.digitalsmiths.com/ Wizzard Media http://www.wizzard.tv/ YuMe ...
