According to WebSideStory's StatMarket.com as of December 10, 1999, 17.5% of users are accessing the Web behind proxy servers (based on sample of 35M users). This represents an increase of over 15% since April 1999 (when approximately 15% of users were behind proxies).
Caching Market Projections
According to an August 1999 Internet Research Group report cited by The Industry Standard, the caching market will grow from $88M in 1998 to $2.1B in 2003. They later (October 1999) cite Network Appliance as the leading caching appliance vendor in 1998, with 28% of the caching market.
A February 2001 article quotes IDC as saying that shipments of caching software will grow at 92% per year between 1999 and 2004, while revenues will increase about 5% faster. In 2003, IDC is quoted as believing that the 2003 caching appliance market will hold steady to the 2002 numbers (which dropped from $426 million in 2001 to just $249 million).
Content Delivery Projections
According to the HTRC Group in 1999, the content delivery network market will grow to $2.3B by 2002. In their more recent 2000 Content Delivery Service Study, they state that CDN services growth is expected to grow from $97 million in 2000 to $2.2 billion in 2003.
In February 2000, the Internet Research Group released a report projecting a $6B content distribution and delivery systems market in 2004. In May 2000 The Yankee Group revised their original projections that content delivery services will only grow to $875M by 2003, and instead predicts $125 million by the end of 2000 and growing to $1.4B in revenue for 2003. A late 1999 TechnologyEvaluation.com research note puts the trend at $500M by 2002. In October 2000, IDC projected the US CDN market to grow to $1 Billion in 2004. More recently, a November report from IDC says that worldwide content network spending will increase from $1.6 billion in 2001 to $8 billion in 2005.

In a January 2003 report, Probe Research predicts that CDN revenues will pick up in 2003, with more than 20% growth (compared to 10% growth in 2002). CDN market will become intermingled with hosting market as each tends to offer the services of the other.
