The ones we call "radio waves".
That's the electromagnetic spectrum between maybe roughly speaking 10 KHz to 300 GHz.,
or wavelengths between 1 mm to 30 km.
Electromagnetic waves carry radio, television, and telephone information.
If we want to add information onto it, we know how to do that. That's how we accomplish radio, TV, GPS, and the cellular telephone system.

They were most likely developed at the same time, since one cannot function without the other. The first TV displays were cathode ray tubes, which existed before TV, so I guess technically you could say the TV came first, but only if you were being a PITA.
