The German Fraunhofer Society, behind the development of MP3, stopped licensing on patents for this codec and, in fact, recognized his death.
According to the developers, although MP3 still remains popular among users, most services, such as streaming channels, TV and radio broadcasting, use more modern ISO-MPEG codecs, such as AAC or MPEG-H. They can provide higher quality sound at a lower bitrate compared to MP3. MP3, short for MPEG-2 Audio Layer III, was first published in 1993, and it was developed from the late 80's. On April 23, 2017, the term of the related patents has expired and license fees are no longer charged.
