CBS's The Challenge: USA beats out all other shows to top the Promo Mojo ranker for the week ended Sunday, August 13. CBS also grabs fifth place to promote Big Brother.

Rounding out the ranking: ABC, which gives some love to Good Morning America in second; TLC, which hypes 90 Day: The Last Resort in third place; and HGTV, which builds excitement for the new season of Ugliest House in America in fourth.

Notably, Big Brother has the highest iSpot Attention Index (118) in the ranking, meaning viewers were on average highly likely to watch its promos all the way through (vs. interrupting viewing by changing the channel, pulling up the guide, fast-forwarding or turning off the TV).

Brief by Promax has partnered with Broadcasting & Cable and iSpot.tv on weekly chart Promo Mojo, offering data revealing the week's most-promoted programming ranked by TV ad impressions.
