Immediate Response (within 2 days) is required.

I am looking for the annual sales revenue and the total number of
companies present in the following industry verticals. I only focus on
the U.S. market and the period of 2000-2005.

1) E-commerce
2) Financial/Banking
3) Technology
4) Corporate/Manufacturing
5) Advertising
6) Media
7) Online Gaming

Must provide solid source information and internet links. Solid source
of information means a renowned research institution or government
agency.

1) E-commerce
source:Forrester Research
current : American consumers spent $172 billion shopping online in 2005
	e-commerce sales rose 23.8 percent in 2004 to $141.4
trend: '... US online retail sales (will grow) from US$172 billion
this year(2005) to US$329 billion in 2010,' says Forrester's
vice-president Carrie Johnson. The increase translates to a solid 14
per cent annual growth rate over the next five years.
E-commerce will represent 13 per cent of total US retail sales in 2010

I also suggest that you have a look at the regular ECOMMERCE reports:
for 2000, 2001 and 2002 - use the tables and texts from:
http://www.census.gov/eos/www/archives.html
2003 - http://www.census.gov/eos/www/papers/2003/2003finaltext.pdf
The data on 2004 & 2005 can be found for each quorter "
4Q 2005 | 3Q 2005 | 2Q 2005 | 1Q 2005 | 4Q 2004 | 3Q 2004 | 2Q 2004 | 1Q 2004

2) Financial/Banking, 3) Technology and Corporate/Manufacturing  and
Advertising and MEDIA, are too widely defined and it is impossible to
determine any numbers here. If your question is phrased differently :
"The total number of corporate companies?". WHat do you actually ask ?
7) Online Gaming
A March 2000 study of close to 30,000 Internet users by the Angus Reid
Group estimates the United States represents only 39% of the estimated
275 million Internet users worldwide. By the end of 2001,
approximately 52 million people globally wagered over $3 billion on
Internet gaming. On average, the casinos keep about 75% of the money
deposited
According to Bear Stearns, online gaming was expected to exceed $8
billion in revenue by 2002. Datamonitor predicted online gaming worth
was $6.5 billion in 2002, reaching $8.25 billion in 2003 and $11
billion in 2004. It is expected to reach $125 billion by 2015.

Subscription - Worldwide online game subscription revenue grew 43 per
cent to $2 billion US in 2005, according to a video gaming market
research firm.
Online subscriptions remain a fraction of the estimated $29 billion US
in overall video game sales in 2005, but San Diego, Calif.-based DFC
Intelligence expects the segment will reach $6.8 billion in sales by
2011.
