Barack Obama's 30-minute infomercial scheduled for three of the four leading broadcast networks Wednesday will air simultaneously on Univision as well. The extended promo will run with a simultaneous Spanish voiceover.

NBC, CBS and Fox are airing Obama's lengthy pitch to a national audience six days before election day. ABC is apparently a holdout, preferring to go with its regular Wednesday schedule--which could yield higher revenues than the Obama presentation.

The campaign is paying the three English-language broadcasters about $1 million each to rent the time, from 8 p.m. to 8:30 p.m. in the Eastern and Pacific time zones. If there is a World Series sixth game on Fox, it will air after its conclusion in the West.

Contacted recently, Univision competitor Telemundo said the Obama campaign was not planning to air the ad on the network.

The Obama campaign is apparently using the Univision presence in part to help it garner support from Hispanic voters in Nevada, Colorado and Florida--where it is trying to win the traditionally Republican-leaning states.

Word that Univision would air a version of the Obama ad was first reported by WashingtonPost.com, and apparently was announced by Miami Mayor Manny Diaz.

This news story is important. I recommend that everyone read it.
