(Reuters) - The U.S. government tapped into computer networks of companies including Google Inc. and Brazilian state-run oil firm Petroleo Brasileiro SA, according to leaked U.S. documents aired by Globo, Brazil's biggest television network.

A week after it broadcast a report that the U.S. National Security Agency spied on the presidents of Brazil and Mexico, Globo said the agency had also spied on major companies.

It showed slides from an NSA presentation, dated May 2012, that it said was used to show new agents how to spy on private computer networks.
