Computer unveiled the first generation iPod, a 5 GB hard drive based DAP with a 1.8" hard drive and a 2" monochrome display. With the development of a spartan user interface and a smaller form factor, the iPod was initially popular within the Macintosh community. In July 2002, Apple introduced the second generation update to the iPod, which was compatible with Windows computers through Musicmatch Jukebox. iPods quickly became the most popular DAP product and led the fast growth of this market during the early and mid 2000s. In 2002, Archos released the first "portable media player" (PMP), the Archos Jukebox Multimedia with a little 1.5" colour screen. Manufacturers have since implemented abilities to view images and play videos into their devices. The next year, Archos released another multimedia jukebox, the AV300, with a 3.8" screen and a 20GB hard drive. In the same year, Toshiba released the first Gigabeat. In 2003, Dell launched a line of portable digital music players called Dell DJ. They were discontinued by 2006. The name "MP4 player" was a marketing term for inexpensive portable media players, usually from little known or generic device manufacturers. The name itself is a misnomer, since most MP4 players through 2007 were incompatible with the MPEG-4 Part 14 or the .mp4 container format. Instead, the term refers to their ability to play more file types than just MP3. In this sense, in some markets like Brazil, any new function added to a given media player is followed by an increase in the number, for example an MP5 or MP12 Player, despite there being no corresponding MPEG-5 standard (, the current standard, still being developed, is MPEG-4). iriver of South Korea originally made portable CD players and then started making digital audio players and portable media players from 2002. Creative also introduced the ZEN line. Both of these attained high popularity in some regions. In 2004, Microsoft attempted to take advantage of the growing PMP market by launching the Portable Media Center (PMC) platform. It was introduced at the 2004 Consumer Electronics Show with the announcement of the Zen Portable Media Center, which was co-developed by Creative. The Microsoft Zune series would later be based on the Gigabeat S, one of the PMC-implemented players. In May 2005, flash memory maker SanDisk entered the PMP market with the Sansa line of players, starting with the e100 series, and then following up
