In June 1922, a couple of 50-watt radio stations were established in Pasay and in Manila by Henry Hermann.During that time, the Filipinos readily accepted radio news and entertainment programs, and local businessmen, who recognized its profitability, established their own radio stations to advertise their products and services.
• In 1924 an American established the first AM radio station named KZKZ.HENRY HERMANN ------was the founder of the Electrical Supply Company (Manila). He gained permission, possibly from local government and the military to operate more than one station..
• Two years into the experiment, Hermann replaced the experimental stations with a 100-watt station with the call letters KZKZ.• On October 4, 1924, with KZKZ but a few months old, he sold it to the Radio Corporation of the Philippines (RCP)
In 1929, KZRC, RadioCebu, opened in Cebu andintroduced radio broadcastingin the province. However, itwas closed down becauseshortwave relay signals wereunsuccessful between Cebu andManila. It reopened after adecade and fearlessly went onair with the guerillamovements.

• The Philippines history in terms of a free press is a checkered past. In the beginning, the news was censored by the Americans. Later under the Americans, the Philippines press was open and free-wheeling before martial law was imposed under President Ferdinand Marcos in 1972.
