Task: Question Generation
Input (English): Jobs stated during the Macintosh's introduction "we expect Macintosh to become the third industry standard", after the Apple II and IBM PC. Although outselling every other computer, it did not meet expectations during the first year, especially among business customers. Only about ten applications including MacWrite and MacPaint were widely available, although many non-Apple software developers participated in the introduction and Apple promised that 79 companies including Lotus, Digital Research, and Ashton-Tate were creating products for the new computer. After one year, it had less than one quarter of the software selection available compared to the IBM PC—including only one word processor, two databases, and one spreadsheet—although Apple had sold 280,000 Macintoshes compared to IBM's first year sales of fewer than 100,000 PCs.
Output (English): How many Macintoshes had Apple sold after one year?
