Radio gave the tower more work to do
A temporary exposition structure became a useful transmitter.
The Eiffel Tower was built for the 1889 exposition with an initial permit lasting twenty years. Scientific work gave it uses beyond the fair, especially radio transmission. Antennas and nearby radio facilities made its height useful. Standard-time signals from the Paris Observatory were broadcast from the tower. These continuing uses helped keep it standing after its exhibition role ended.
