What it means
つつある expresses that an action or change is currently in progress, often with a sense of gradual development toward a new state. It attaches to the masu-stem of a verb and is common in formal writing, reports, news, and presentations. It usually describes an ongoing change rather than a single, completed action.
Usage note
つつある is more formal than ている and is especially natural for gradual or developing changes. The polite sentence-ending counterpart is つつあります.
