Opera, looking to gain a foothold in the mobile browser market, introduced a new initiative called Sponsored Web Pass, a new version of the pay-as-you-go Web Pass service that provides free Internet in exchange for watching sponsored messages. Advertisers work with the operators to select the best ad packages for potential viewers, and any offers that are acquired by users within these packages are only redeemable within Opera’s browser, keeping users within the app. It’s an interesting take on in-app purchases, and indeed presents a different way for advertising companies to target their audience specifically on mobile.
