Motorola has exceeded Apple in brand loyalty among men ages 18-and-up since the launch of its new Droid handset, but the iPhone maker has remained well ahead of competitor BlackBerry, according to one study.

According to new, daily tracking statistics from YouGov's BrandIndex, Apple dropped from a peak score of 48.1 in the month of November to a score of 22 last week. That took it below Motorola, which remained relatively static from its month-long peak of 32.3, finishing last week with a score of 29.3.

The study's scale ranges from -100 to 100, based on interviews conducted with 5,000 people each weekday from a representative U.S. population sample. YouGov conducts more than 1.2 million interviews per year, selected from an online panel of more than 1.5 million unique individuals. The study has a margin of error of +/- 2 percent.

The company said its survey demonstrates that Motorola has likely come out on top of the ongoing advertising dispute between Verizon and AT&T.

"Motorola has seen its brand loyalty unaffected by AT&T's lawsuits against Verizon Wireless and ad war bashing," YouGov said. "But it seems to have taken a toll on Blackberry, which has withered under all the Droid/iPhone marketing and hype."



This week, Apple indirectly joined the dispute with two new ads that tout features available only on AT&T's UMTS/GSM network. The advertisements debuted after the most recent study results from YouGov were released; any potential impact from the ads likely wouldn't be seen for weeks.

It's a similar story to earlier this month, when Verizon's brand perception soared while AT&T sunk in the 18- to 34-year-old target demographic. The study suggested that Verizon and Motorola's advertising campaign for the Droid, which launched on Oct. 18, proved effective. Those ads, along with network-specific TV spots from Verizon, directly targeted both Apple's iPhone and AT&T's coverage.
