Nothing very practical was developed for anti-aircraft purposes until WW1, when the British decided a few weeks into the conflict that something was needed to dissuade the Germans from flying over their coasts with Zeppelins; the QF 1-pounder "pom-pom" was the first artillery piece designed as a dedicated anti-aircraft (AA) gun. Soon, everyone had some type of "ack-ack" to fire at the growing number of warplanes buzzing about, both on the battlefield and on the home front.
