Media Metrix Expands into Mexico 12/10/2000 US-based Internet research group Media Metrix aims to launch operations in Mexico in the second quarter of 2001. Media Metrix started operations in Brazil just recently, but has not entered any other Latin American markets so far. In January 2001, the company plans to start recruiting ‘panellists’ in Mexico in order to measure Internet usage and attitudes. To enter the Mexican market, Media Metrix is looking to link up with Bimsa-Ipsos, the local Ipsos subsidiary. Ipsos is already Metrix's partner in Brazil.
