## 1 History and Development

### 1.1 Launch and Early Statistical Translation

Google Translate was launched in April 2006 as a free multilingual machine translation service. Initially, it supported only a handful of language pairs—Arabic, Chinese (Simplified), English, French, German, Italian, Japanese, Korean, Portuguese, Russian, and Spanish—using statistical machine translation (SMT) technology. The system relied on bilingual text corpora and statistical models to generate translations, with performance heavily dependent on the availability and quality of parallel data.

### 1.2 Transition to Neural Machine Translation (2016)

In November 2016, Google announced a major upgrade: the adoption of neural machine translation (NMT) under the name Google Neural Machine Translation (GNMT). This shift replaced the earlier phrase‑based SMT system with an end‑to‑end neural network, significantly improving fluency, context handling, and overall translation quality. The rollout began with English‑to‑French, English‑to‑German, and other high‑resource language pairs, and gradually expanded to all languages over the following months.

### 1.3 Expansion of Language Coverage

From its initial 11 languages, Google Translate has grown to support over 130 languages as of 2025. The expansion has included major world languages (e.g., Hindi, Arabic, Spanish), regional languages (e.g., Catalan, Basque), and lesser‑known languages (e.g., Maori, Cherokee). In 2024, Google added 110 new languages to its service via its PaLM 2 large language model, including many indigenous and underrepresented languages.
