From Bell's call to smartphones: 150 years of telephone evolution

One hundred fifty years ago, on March 10, 1876, Scottish-American inventor Alexander Graham Bell made the first telephone call in Boston, using his newly patented device to contact his assistant in an adjacent room. That simple voice transmission over copper wire sparked a revolution that would ultimately connect the entire world, evolving from a novelty into an indispensable tool that now commands a significant share of humanity's daily attention.

Early expansion

The early technology was initially used for short-distance communication between rooms but quickly expanded across the United States through pole-mounted cables, enabling Bell and his assistant to make the first transcontinental telephone call in 1915. The technology reached the Ottoman Empire by 1908, and in 1926, the Republic of Türkiye established its first automatic telephone exchange in Ankara under the direction of the country's founder Mustafa Kemal Atatürk. The invention required several more decades to mature into a common household utility before advances in satellite and wireless technologies gradually reduced dependence on physical cables.

Mobile revolution

The modern era of mobile communication began in 1973 when Motorola executive Martin Cooper demonstrated the world's first portable mobile phone, paving the way for commercial cellular devices a decade later. Technological change accelerated with the arrival of camera phones in 1999, followed by the introduction of touchscreen smartphones in 2007. Over time, mobile phones evolved from basic communication tools into central platforms for social interaction, education, commerce and entertainment as internet speeds and digital services expanded worldwide.

Global reach today

According to the Digital 2026 report by We Are Social and Meltwater, approximately 5.78 billion people globally now use mobile phones, representing roughly 70% of the world's population, with smartphones accounting for nearly 94% of active mobile devices. The rise of smart technology has significantly increased time spent online compared with the early years of mobile phones, when usage was limited by high costs and basic functionality. The report found that people worldwide spend an average of six hours and 43 minutes connected to the internet each day, with mobile devices accounting for four hours and two minutes of that time. Around 60% of global internet traffic now comes through mobile phones.

Türkiye above global averages

In Türkiye, digital usage exceeds global averages. Internet users spend around seven hours and 15 minutes online daily, including four hours and 35 minutes using smartphones and nearly three hours on social media applications. The average global user spends nearly two and a half hours per day scrolling social media platforms on their phones, demonstrating how the device has transcended its original purpose as a voice transmitter to become a gateway to the digital world.
