What is DSL?
Types of DSL
|History of DSL
When DSL was first developed in 1989 it was designed primarily for video. ADSL was the flavor of choice because it provides the high downstream rates needed for streaming video. Video on Demand (VOD) was viewed as the next generation service supporting the next generation network from telephone companies around the world. Video on Demand was expected to be the telephone company's way of competing with cable television providers, and ADSL was the technology to make it possible. However, with few exceptions, VOD has not proven to be as popular as was once predicted. Instead, the market for DSL has emerged much differently than was once expected. As it turns out, personal computer users need high-speed access to the Internet and corporate networks from residences and remote offices. Now, this PC user market has captured the attention of both cable TV providers and telephone companies, as both are furiously working to meet their needs.
