The EU Commission announced in November that it has sent formal antitrust charges to CRT tube manufacturers, due to suspicion that they operated a cartel. Royal Philips Electronics NV, a Dutch electronics company, confirmed that it had received the Commission's charges and was preparing a response. The Commission stated its cartel investigation into TV screen makers in 2007, in collaboration with Asian antitrust authorities, because of suspicions that manufacturers were fixing prices of the tubes. During the probe, several offices were raided, including those of Philips and Matsushita Electric Ind Co. In May 2008, a related investigation carried out by Hungary's competition authority GVH launched a cartel probe into CRT manufacturers on the EU market because of price fixing suspicion between 1995-2007.
