Microsoft TechNet is a Microsoft program and resource for technical information, news, and events for IT professionals. Along with a website, they also produce a monthly subscription magazine titled “TechNet Magazine”.
TechNet was originally available only to customers with paid subscriptions; however, it has been expanded to include public information, webcasts, local events, and free newsletters. They have also started an open source blog on April 6, 2006 called Port 25 to publicly explore that business model and provide discussion forums.
On July 1, 2013, it was announced on the TechNet website that Microsoft is discontinuing the TechNet subscription service, with the purchase and renewal of subscriptions to be closed by August 31, 2013, in favor of free services such as the TechNet Evaluation Center.
