Also during Sunday's game, the website-publishing platform Squarespace ran an ad featuring the actor Jeff Bridges, a longtime antihunger activist. Through DreamingWithJeff.com, a Squarespace site, Mr. Bridges is streaming and selling "Jeff Bridges Sleeping Tapes," restful sounds, guided mediations, and stories designed to lull listeners to sleep. All proceeds from sales will go to the No Kid Hungry campaign waged by Share Our Strength. Web users who stream the tapes will be prompted to donate whatever they'd like to the campaign. The company recruited the actor about doing the ad and the tapes as a way to generate buzz about the company, according to Bill Shore, Share Our Strength's leader. The actor agreed on the condition that proceeds go to No Kid Hungry. "We've done a lot of cause-related marketing," said Mr. Shore with a chuckle, "but this is really one of a kind."
