After the telephone was developed in the mid-1870s, and radio at the turn of the century, it was natural to seek ways to combine the two, merging radio's mobility with the telephone's person-to-person capability and extensive network. Ship-to-shore radiotelephones were available as early as 1919, and the next decade saw the arrival of two- way radios for police cars, ambulances, and fireboats. These public- safety radios were mobile, but they were limited by the range (usually small) of the transmitter, and they connected only with fellow users, not with every telephone subscriber. Also, like all radio equipment of the day, they were big and clunky; Dick Tracy's two-way wrist radio existed only in the funny pages.
