Personal computer company IBM will be 100 years old on Thursday, and to celebrate up to 400,000 employees worldwide will skip the usual office work in order to donate time to charitable causes and schools.
IBM has also launched a website to celebrate 100 years in the industry. The 30th anniversary of the unveiling of IBM's first consumer PC will also be celebrated on 12 August.
IBM's PC, released in 1981 and called the IBM 5150, is widely consider to be the first home PC because of its affordability - it sold for US$1565. It won Time Magazine's 'Machine of the Year' award for 1982. The award did not exist; that year the IBM 5150 replaced Time's 'Man of the Year'.
The cheapest IBM 5150 had 16KB of RAM and no floppy disk drives, but an expanded version was also available with 256KB RAM and two floppy drives.
