Osborne style, consumers decided to wait for the new Amigas and Commodore had to close their Australian office in face of plummeting sales. At the same time, Commodore's foray into the highly competitive PC market was unsuccessful. This contributed to Commodore's 1992 profits falling to an unimpressive $28 million, and made the need for a successful new Amiga launch all that more critical. In October 1992, Commodore released the Amiga 1200 and the Amiga 4000. Each featured the new AGA chipset and the third release of AmigaOS. Computer Gaming World reported in March 1993 that declining Amiga sales were "causing many U.S. publishers to quit publishing Amiga titles", and in July that at the Spring European Computer Trade Show the computer was, unlike 1992, "hardly mentioned, let alone seen". That year Commodore marketed the CD32, which was one of the earliest CD-based consoles and was also the world's first 32-bit game machine, with specifications similar to the A1200. The last Amiga (and the last computer) released by Commodore was the A4000T, in 1994. Amiga in the United States Mass-market Amigas were considerably cheaper than PCs and Macintoshes at the time. This factor helped to boost sales in European markets, but it also continued Commodore's misfortune of being viewed in the more price-conscious US markets as a producer of cheap "toy computers" and "game machines". This perception was furthered by the fact that most Commodore retail outlets were toy stores, and marketing campaigns were mismatched with the public's needs and wants. Overall, the Amiga was very successful in Europe, but it sold less than a million units in the US. Additionally, in the US market, the IBM PC was already a dominant market force, especially in the workplace. Potential buyers' first question was often, "Is it IBM compatible?", allowing the user to "take work home" or more often, take software home to install on their own machines. To satisfy these users, Commodore introduced a variety of PC-compatibility add-ons, such as the Amiga Sidecar for the Amiga 1000, the Bridge Board for the A2000, and a 5.25" floppy disk drive to facilitate data exchange with PC disks. Even as Commodore was improving the Amiga's interoperability, the PC's graphics drastically improved from the early mediocre CGA and EGA modes prevalent at the Amiga's introduction to VGA and SVGA, which appeared to match or exceed the Amiga's abilities. This caused a raft of PC
