The brand and marketing analytics firm released its BrandZ Top 100 report (PDF) today, pronouncing Google (GOOG) the number one brand for the third consecutive year. The company’s brand equity: $100 billion, a first for the study.

While Google dominated the study’s rankings, it wasn’t the only tech company to make it into the top 100 or the top 10, for that matter. Microsoft (MSFT), IBM (IBM), Apple (AAPL), China Mobile and Vodafone (VOD) topped the list as well, ranking second, fourth, sixth, seventh and ninth respectively.

“Five of the top 10 in the BrandZ Top 100 are technology brands,” Millward Brown Optimor said in its report. “The rapid ascent of these brands and their high values reflect the strength and velocity of the technology category, which grew by 2 percent last year,” the report reads. “The rising popularity of online search advertising, which is cheaper than display, is benefiting Google which owns 73 percent market share in this area.”

According to the market research firm’s assessment of financial performance and consumer sentiment, Google’s (GOOG) brand alone is worth some $86 billion–$14.6 billion more than GE’s (GE) and $15.2 billion more than Microsoft’s (MSFT). Impressive. Especially since that $86 billion represents a 30% jump from 2007.

That said, Google is not the big winner in the year-over-year increase in the tech brand-value competition. That honor belongs to Apple (AAPL), whose brand grew in value by 123%.

The big losers? No surprises here, either. Yahoo’s (YHOO) brand slipped 13% in value year-over-year, Motorola’s (MOT) 30%.
