It seems there might be some confusion regarding the event you are referring to. The first successful transatlantic telegraph cable operation did not occur on June 24, 1848. The first successful transatlantic telegraph message was actually transmitted in 1858. Nevertheless, here is a brief overview of the significant development surrounding the transatlantic cable:

The First Transatlantic Telegraph Cable (1858)

Background

The idea of a transatlantic telegraph line was a monumental vision in the mid-19th century, intending to connect the communication networks of Europe with North America to enhance diplomatic, commercial, and personal communication.

Key Developments Prior to 1858

• Initial attempts to lay down submarine telegraph cables in shorter distances had been made and proven successful in the 1850s, such as the English Channel cable in 1851.
• The endeavor was spearheaded by American businessman Cyrus West Field who, along with the Atlantic Telegraph Company, garnered international support and funding for this ambitious project.

Successful Completion

• The first successful transatlantic cable was laid between Western Ireland and Newfoundland, Canada, in August 1858 after initial failures and a complex and costly process that took years of trial and error.
• The cable, measuring over 2,500 miles, required numerous advances in cable design and engineering.

First Transmission

• The first message transmitted on August 16, 1858, was a formal greeting from Queen Victoria of the United Kingdom to President James Buchanan of the United States.
• The message took 17 hours to transmit, but it marked a turning point in global communication, drastically reducing the communication time between Europe and North America from weeks to mere minutes.

Aftermath and Consequences

• The initial 1858 cable ceased functioning after only three weeks due to voltage issues, emphasizing the need for further innovations.
• Subsequent successful cables were laid with advancements that improved reliability, notably in 1866, when a more durable cable was completed using refined materials and technologies.

Broader Historical Significance

• The transatlantic telegraph cable significantly impacted international relations, commerce, and the development of global communication networks.
• It heralded an era of instant communication, fundamentally altering economic and political landscapes across continents.
