In a move that illustrates how television networks are girding for a protracted battle with striking TV writers while also scrambling to fill major programming holes, interactive karaoke restaurant Spotlight Live is closing in on a production deal, The Post has learned.

According to three sources familiar with the situation, broadcast networks ABC, CBS, NBC, The CW and a handful of cable networks held informal talks with Spotlight founder Jen Worthington before the writers strike began about developing a TV show based on Spotlight’s concept.

A source inside NBC said the network thought Spotlight, a Times Square club and restaurant that features five professional recording booths and provides professional backup singers and dancers for would-be performers, might be a nice fit with the network’s theme parks, or could be a show broadcast on cable or video-on-demand.

While informal at first, sources said the networks’ talks with Spotlight, which is being repped by Creative Artists Agency, have ramped up since the writers strike began Nov. 5, and a deal could be in place in time for 2008’s mid-season.

Spotlight’s talks with the networks have intensified as the antagonism mounts between networks and striking TV writers, and as network sources privately say they don’t expect a resolution to the strike before March.

Worthington declined comment for this story. The networks mentioned either declined comment or could not be reached for comment.

Prior to the beginning of the strike, the networks ordered a plethora of reality-show programming that they hoped would tide them over until a deal was reached. But with a resolution not expected anytime soon, sources said the networks will likely need to greenlight additional reality-show programming.

Each new reality-show deal accomplishes two goals for the networks. First, because reality shows don’t employ writers, they fill the void created by scripted programming that has been halted or canceled due to the strike. Second, it signals to writers that the networks can withstand a strike indefinitely.

Spotlight, where Jennifer Lopez and Alicia Keys have performed, already has some powerful partners on the music and Internet side of its business in SonyBMG’s Epic Records and cable company Comcast, respectively.

Epic has agreed to provide studio time and to record, produce, distribute and market a single from eight winning singers selected by Spotlight’s diners, an online audience and Epic judges. Comcast streams videos of the performers through its Ziddio unit.
