However, telegrams were never able to compete with the letter post on price, and competition from the telephone, which removed their speed advantage, drove the telegraph into decline from 1920 onwards. These systems led to new telegraph codes, starting with the Baudot code. Traffic became high enough to spur the development of automated systems- teleprinters and punched tape transmission. Telegrams became a popular means of sending messages once telegraph prices had fallen sufficiently. Wireless telegraphy developed in the early 20th century became important for maritime use, and was a competitor to electrical telegraphy using submarine telegraph cables in international communications. The heliograph was standard military equipment as late as World War II. The most extensive heliograph network established was in Arizona and New Mexico during the Apache Wars. It was mainly used in areas where the electrical telegraph had not been established and generally used the same code. The heliograph is a telegraph system using reflected sunlight for signalling.

The Morse system was adopted as the international standard in 1865, using a modified Morse code developed in Germany in 1848.

The electric telegraph was slower to develop in France due to the established optical telegraph system, but an electrical telegraph was put into use with a code compatible with the Chappe optical telegraph. This was quickly followed by a different system developed in the United States by Samuel Morse. It was first taken up in Britain in the form of the Cooke and Wheatstone telegraph, initially used mostly as an aid to railway signalling.

The electric telegraph started to replace the optical telegraph in the mid-19th century. The system was used extensively in France, and European nations occupied by France, during the Napoleonic era. The earliest true telegraph put into widespread use was the optical telegraph of Claude Chappe, invented in the late 18th century.
