Lesbian and gay purchase consideration for non-sponsoring advertiser Chevrolet is actually way up, according to YouGov BrandIndex. Chevy ads showed gay and bi-racial couples. They didn’t give Chevrolet a big boost among the general population, though. Chobani got a higher lift in purchase consideration and more positive buzz than any other official sponsor. Chobani also grew word of mouth more than any sponsor but Coca-Cola.
