The enduring change in internet usage habits is fundamentally associated with the development of mobile-friendly interfaces and domestic internet usage trends. The widespread use of mobile devices has had a significant impact on people's online preferences and behaviors worldwide. Similar processes are observed in Hungary, where mobile usage has become increasingly important among internet users. In this article, we examine the role of mobile-friendly interfaces in internet usage trends, as well as the evolution of domestic internet preferences.
II. The role of mobile-friendly interfaces in Internet usage trends
The rapid growth of smartphones and tablets has greatly contributed to the frequency of mobile use. Most of us carry our mobile phones with us at all times, allowing us to access the internet anytime and anywhere. Consequently, it's not surprising that people increasingly browse the internet, seek information, make purchases, and communicate via mobile devices. This change has inspired businesses to improve and optimize their websites and applications for the mobile experience.

In Hungary, more than 90% (specifically 91%) of internet users used smartphones for internet access, indicating the popularity of smartphones and the gradual rise of mobile usage (MediaWatch Ltd., 2021). People consider smartphones convenient, and portable, providing quick access to desired content. They primarily use their smartphones for social media (68%), handling emails (54%), and online shopping (48%). Applications are also highly popular among internet users, preferred by 79% of users, but browser-based internet usage remains significant (71%) (MediaWatch Ltd., 2021). Therefore, businesses need to focus on developing mobile applications and creating mobile-friendly browser interfaces to effectively reach users and meet their internet usage preferences.

Responsive design is crucial, allowing websites and applications to adapt flexibly to different screen sizes and devices. This ensures uninterrupted and pleasant user experiences across any device.

Convenient purchasing and online interactions through mobile devices are also essential for user satisfaction and retention on a given platform.

Moreover, mobile-friendly interfaces help businesses gain a competitive edge in the online space and build a positive brand image as users enjoy better experiences.
