Podcast network Wizzard Media announced today that they have archived over 118 million words using their proprietary “admatch” technology process. Of those, they have identified more than 10,000 words as keywords with potential significance to prospective advertisers. The database of keywords was populated by processing over 800,000 hours of audio and video programming available on the Wizzard Media Network.

“This is a huge accomplishment for our publishers. Search marketing plays a major role in the plans of most advertisers and we are positioning our publishers to participate in this advertising marketplace.” said Chris Spencer, CEO, Wizzard. “This tool [also] plays an important role for consumers in the discovery of new shows which can significantly accelerate audience growth.”

Paid search continues to garner the largest chunk of the online ad industry, according to eMarketer’s online ad spending report from November of last year. The report noted that paid search’s share of online ad spending will continue to hover in the 40% range through 2011, accounting for more than $50 billion over the next four years.
