Malaysia's attitude towards the Internet continues to be ambivalent.
On the one hand, the country recognizes the Internet's importance towards developing a modern knowledge economy, and has set up a high-tech zone called the Multimedia Super Corridor (MSC) to drive the country's online initiatives.
On the other, conservative politicians from Prime Minister Mahathir Mohamad downward remain concerned about "negative uses" of the Internet, such as spreading of false rumors. Several Malaysians were jailed on the basis of e-mail messages of this type they had sent during the 1998 political crisis caused by the government's prosecution for corruption of then Deputy Prime Minister Anwar Ibrahim.
The e-mails, and the identity of their senders, were passed on to Malaysian police by a compliant ISP (Internet service provider), but Malaysians continued to use the Web as their only way of bypassing the government-controlled print media.
