Answer:
Satellite is probably the most useful invention since the wheel. Satellites
have the capability to let you talk with someone across the nation or let you
close a business deal through video communication. Almost everything today is
heading towards the use of satellites, such as telephones. At&t has used this
communications satellite (top right) ever since the late 1950s. TVS and radios
are also turning to the use of satellites. RCA and Sony have released satellite
dishes for Radio and Television services. New technology also allows the
military to use satellites as a weapon. The new ION cannon is a satellite that
can shoot a particle beam anywhere on earth and create an earthquake. They can
also use it's capability for imaging enhancement, which allows you to zoom in on
someone's nose hairs all the way from space
