The revision is the first time that Yahoo has made a significant change to its logo since a few tweaks shortly after co-founders Jerry Yang and David Filo incorporated the company in 1995.
Mayer's overhaul of Yahoo has attracted a lot of attention, but so far it hasn't provided a significant lift to the company's revenue. Yahoo depends on Internet advertising to make most of its money, an area where the company's growth has been anemic while more marketing dollars flow to rivals such as Google Inc. and Facebook Inc.
Yahoo's stock has climbed by nearly 80 percent, but most of that gain has been driven by the company's 24 percent stake in China's Alibaba Holdings Group. Investors prize Alibaba because it has emerged as one of the fastest growing companies on the Internet.
