History
Opera 2.0 was the first version of the browser released to the public. Its predecessor, MultiTorg Opera 1, was only intended for internal usage.

Until Opera 5.0, the browser was available free as a 30-day trial. After the trial expired, the user was forced to pay for the browser to continue using it. With Opera 5.0, released in 2000, the browser was no longer tied to a trial. It has become free to use, however it showed banners with either text-based personalized ads by Google or a stock banner of Opera Software to pay for the ad-free edition.

Opera 76 is the first version of Opera that works with Macs with the Apple M1 SoC.
