NTT Docomo launched i-mode in 1999, which was the world's first commercial mobile internet service based on packet-switched technology. I-mode offered "always-on" internet access through features like email, browsing, and downloads via a mini-browser on mobile phones. By utilizing compact HTML (cHTML) and working with partners, i-mode was able to quickly grow and become popular in Japan with over 30 million users by 2001. However, growth stagnated after 2002 with the rise of competitors and consumers beginning to access the internet via PCs more than mobile phones.
