I could not agree more with Mark and following Dan example.
Branding overall is half the game. Its an extremely powerful tool, but you need to know how to use it properly. Web hosting is not an innovative niche, thus creating something out of ordinary is quite a challenge. There are 100s of companies dreaming up the same, who also have the budget to spend a lot on marketing. The goal here is to create a name for yourself using a particular service or product nobody else does and market it until the wheels fall off.
For example, when you think of a "soft drink" you thing of Coca Cola. They might not have invented the product per se, but they were the first to spend billions on marketing the association of "soft drink" with their company name.
Rackspace, as Dan mentioned, is known for their "high end" products. I believe previously their also coined the phrase "Fanatical support". I also remember "Rollover bandwidth" which I believe HostRocket introduced first and a lot of companies followed...
