In the wake of the tragic events in the US, charitable donations ranging from $1 to $10m have been bestowed on the emergency workers and survivors of the terrorist attack.
Companies like General Electric and Cisco Systems are leading the way with $10m and $6m pledged respectively. The Bill & Melinda Gates Foundation is donating $1m to the September 11th Fund, which has been set up by the United Way of New York City and the New York Community Trust.
Amazon.com's online fundraising has already pulled in another million dollars, and Microsoft has pledged $5m in cash and $5m in software and services to help government agencies and relief groups.
The software giant has also encouraged its employees to make personal donations, for which Microsoft will make matching donations of up to $12,000 per employee annually.
Rick Belluzzo, president and chief operating officer at Microsoft, said: "We are all stunned by these tragic events. Our hearts go out to the victims and their families, and everyone affected by this terrible situation."
Dupont announced that it would donate $5m to be used primarily for the education of the children of fire-fighters, police officers and other uniformed emergency response personnel who lost their lives as a result of the attack.
New York City United Way said that, within a 24-hour period from midday Tuesday to midday Wednesday, the organisation collected $15m, including $175,000 donated online.
And IDG's Computerworld announced a volunteer IT programme to collect information from companies and individuals with technology goods, services or expertise to offer in support of the disaster relief efforts in New York.
The information will be shared with volunteer agencies that specialise in technology work and government and relief agencies.
Furthermore, America's largest private philanthropist foundation, the Lilly Endowment in Indianapolis, pledged $30m to three organisations: the American Red Cross, the Salvation Army and the September 11th Fund.
Employees from Cisco, Oracle, Applied Materials, Compaq, Akamai, Metrocall, 3Com, Sun Microsystems and Bea Systems were among those on the four doomed flights.
