Opera was first released on Monday, April 10th 1995, making it one of the oldest desktop web browsers to ever exist. It was commercial software for its first ten years and had its own proprietary layout engine, Presto. In 2013, it switched from the Presto engine to Chromium. In 2016, Opera, developed in Norway, became a subsidiary of an investment group led by a Chinese consortium.[20] In 2018, Opera Software went public on the NASDAQ stock exchange. By the end of 2022, the consortium sold all of its shares, and Opera in turn committed to repurchase all of its American Depository Shares to reestablish its corporate autonomy. As of the end of 2023, Opera Software was 72.4% owned by Kunlun, a Chinese public company, making it a subsidiary of that company. Opera CEO James Yahui Zhou is a controlling shareholder in Kunlun.[21]
In 2019, Opera introduced Opera GX, a browser marketed towards gamers, claiming to have better performance with a built-in tracker and ad blocker and also having a CPU and RAM usage limiter.[22]
