Yahoo! is planning a massive global marketing campaign with company’s new tagline “It’s You!”. The Y in the “You” is the Y from “Yahoo,” with famous Yahoo exclamation point. The ads are being created by Ogilvy & Mather, a unit of Dublin-based WPP. The global campaign’s focused on personalization and how Yahoo can help people navigate all their services and information online. The company’s also expected to unveil new tools to help users customize Yahoo products like Yahoo.com, which it has recently updated to support links to other third-party software like Facebook. Yahoo declined to comment, noted.
