facilitated mini-games and was concurrent with the NES. Donkey Kong, released in 1981, was a smash arcade hit and market breakthrough for Nintendo. Super Mario Bros., Super Mario Bros. 2, Super Mario Bros. 3, The Legend of Zelda, and the Mega Man series would become major hits for the console. The personal computer experienced explosive growth in the 1980s, transitioning from a hobbyist's toy to a full-fledged consumer product. The IBM PC, launched in 1981, became the dominant computer for professional users. Commodore created the most popular home computers of both 8-bit and 16-bit generations. MSX standard was the dominant computer platform in Japan and in most parts of Asia. Apple Computer superseded its Apple II and Lisa models by introducing the first Macintosh computer in 1984. It was the first commercially successful personal computer to use a graphical user interface (GUI) and mouse, which started to become general features in computers after the middle of the decade. Electronics and computers were also at the forefront of the advertising industry, with many commercials like "1984" from Apple achieving acclaim and pop-culture relevance. Walkman and boomboxes, invented during the late 1970s, became very popular as they were introduced to various countries in the early 1980s, and had a profound impact on the music industry and youth culture. Consumer VCRs and video rental stores became commonplace as VHS won out over the competing Betamax standard. In addition, in the early 1980s various companies began selling compact, modestly priced synthesizers to the public. This, along with the development of Musical Instrument Digital Interface (MIDI), made it easier to integrate and synchronize synthesizers and other electronic instruments, like drum machines, for use in musical composition. High definition television (HDTV) of both the analog and digital variety were first developed in the 1980s though their use did not become widespread until the mid-2000s. In 1981, Hayes Microcomputer Products started selling the Smartmodem. The Smartmodem paved the way for the modern modems that exist today, mainly because it was the first modem to transform what had previously required a two-stage process into a process involving only one stage. The Smartmodem contributed to the rise in popularity of BBS systems in the 80s and early 90s, which were the main way to connect to remote computers and perform various social and entertainment activities before the Internet and the World Wide Web finally became popular in the mid-1990s.
