Love them or hate them, those new Siri ads starring Zooey Deschanel and Samuel L. Jackson are apparently effective, says a YouGov BrandIndex report. As noted by Fortune's Apple 2.0 blog, the celebrity Siri ads are creating buzz among 18-34 year old questioned in the survey.

In just a few weeks, the buzz score for the iPhone went from 16 on April 19 to 51 on May 4, surpassing Android on its way up. The buzz score is based on a survey of consumers who were asked whether they've heard anything about the brand in the last two weeks, either through advertising, news or word of mouth, and whether it was it positive or negative.
