How do television stations broadcast live video across the entire world simultaneously? Please me help!!!

Television broadcasting

The transmission of visual images of moving an stationary objects, generally with accompanying sound, in the form of electromagnetic waves that when received can be reconverted into visual images.

Very high frequency (VHF)

A band of radio frequencies falling between 30 and 300 MHz; VHF signals are widely employed for television and radio transmissions. In the United States and Canada, television stations that broadcast on channels 2 through 13 use VHF frequencies, as do FM radio stations. Many amateur radio operators also transmit on frequencies within the VHF band.
