There is, hams use a small fraction of the available frequencies and the FCC manages all frequencies in the USA to help commercial and non-commercial users share the available frequencies.
So taxis, commercial trucks, FRS radios, radar, fire, police, ambulance, marine radios, cell phones, CB radios, wifi, bluetooth, GPS, time sync services, etc all have allocations managed by the FCC. Similar organizations exist in most (all?) countries.
