By 2025, what mode of communication saw a significant increase in use due to technological advancements?

The correct answer is video conferencing, which experienced a notable surge in use due to advancements in technology. By 2025, improvements in internet speeds, software capabilities, and the integration of advanced features like virtual reality have made video conferencing a preferred mode of communication for both personal and professional interactions. The COVID-19 pandemic had already set a precedent for remote communication, pushing businesses and individuals to adopt video conferencing solutions more widely. These tools facilitate real-time visual communication, enabling more effective collaboration and a sense of connection that texts or emails alone cannot provide.

While instant messaging also increased significantly during this time, its rise was less pronounced compared to the widespread adoption and reliance on video conferencing, especially in corporate environments. Telegrams and postal mail, on the other hand, have generally declined in use as people and businesses move toward faster, more efficient digital communication methods.
