北京电视台
At 19:00 on 1 May 1958; Beijing Television (the predecessor of China Central Television) began its test transmissions, and for the first time, Chinese Communist Party's own TV signals were broadcast in Beijing. On the screens of the few dozen television receivers in Beijing that night, a picture of the headquarters building with the words "Beijing TV station" written on it appeared. On September 2 of that year, BTV broadcast officially for the first time. Later the number of official TV programs increased from twice a week to four times a week (on Tuesday, Thursday, Saturday and Sunday).
