YouTube will use game one of the World Series on Tuesday night to promote its fledgling live pay-TV service with an elaborate ad incorporating live footage.

In a two-minute commercial that will air right before the first pitch, a live shot of the broadcast booth where Joe Buck and John Smoltz will be calling the game will morph into an extended pitch for YouTube TV.

The camera zooms out from the booth to a TV set in someone's living room, which features actual live footage from the stadium.

The rest of the ad will showcase Fox content that's available on YouTube TV and the different ways that subscribers can watch programming through the service.

YouTube TV, a sponsor of the World Series, will also air at least two 30-second spots as well as 6-second ads during each game.

YouTube introduced the service earlier this year, joining an increasingly crowded field of internet-based pay-TV services trying to capture customers uninterested in traditional cable and satellite services.
