LAS VEGAS — Just in time for the launch of midseason, Initiative Media and its partners will be in Las Vegas this week trying to woo international TV buyers attending NATPE into signing up for a new service that measures the amount of buzz American primetime shows are getting.

If there are any headlines, it’s that Fox and NBC midseason shows are garnering the most buzz after both nets stumbled — in Fox’s case, badly — in the fall.

Among the shows measured by PropheSee, the Peacock’s “Law & Order: Trial by Jury” is generating the most interest, with Fox’s “Point Pleasant” in second.

PropheSee is a joint venture of Initiative Media, Trendum and TVTracker.com. Service is targeted at U.S. networks and advertisers, along with international TV buyers.

Initiative exec VP and director of global research integration Stacey Lynn Koerner, who is at NATPE this week, said she has a meeting skedded with Spain’s Endemol Television. She said the PropheSee partners are meeting with other major European buyers, as well as an Australian buyer, but didn’t disclose their names.

No takers yet

So far, no major international buyer or U.S. net has signed up for PropheSee.

The service can tell the international buyer which shows have promise and, later, how a show actually performs and how it may be marketed for an oversea aud, according to Koerner.

“It gives them a relative sense of what will be available in their country and which show might have a longer shelf life,” Koerner said.

PropheSee, which began collecting data in May, correctly predicted that ABC’s “Desperate Housewives” would be a hit.

Of the top 10 midseason shows on PropheSee’s list, NBC has the most at five: “Medium,” “Committed,” “The Office” and boxing reality skein “The Contender,” in addition to “Trial by Jury.”

Fox came in second with three shows: “American Dad” and “The Inside,” in addition to “Point Pleasant.”

CBS’ “Numbers” and ABC’s “Eyes” also made the top 10.
