Both, actually. We create radio waves to transmit data. TV and radio, cell phones and GPS, radar and microwave ovens - all transmit radio waves. We've been doing this constantly for coming up on a century (starting with just the radio waves). But there is a lot of "radio frequency noise" created throughout the universe, mostly in stars. This noise comes in a range of frequencies, and is looked at by astronomers using radio telescopes like the "big dishes" we often see in films and on TV. It's always there, and the radio waves include what is called cosmic background radiation, which is the "echo" or "aftershock" of the Big Bang. It comes from basically "everywhere" in the sky.
