Lenovo, the world’s fourth largest PC manufacturer, is gearing up for a new marketing effort, Ad Age reports.

According to the advertising and marketing news site, Lenovo selected Saatchi & Saatchi of Publicis Groupe for a new campaign over MDC Partners’ Crispin Porter & Bogusky and Oglivy & Mather of WPP.

Ogilvy & Mather has worked with Lenovo “Think” brand products since Lenovo bought IBM’s PC division five years ago. However, a spokesperson for Lenovo said the company, which bases its global headquarters in Morrisville, will continue to work with Ogilvy.

Lenovo introduced a number of new products at the Consumer Electronics Show in Las Vegas last week.
