Just got this piece through Neal Hansch at Macromedia:

Television cable channel HBO, via its interactive agency, has designed a downloadable “skin” for the Firefox Web browser in the custom theme of its upcoming series “Rome“–an 11-episode drama that charts the rise of an Italian empire. The skin, or “theme,” as they are known in Firefox tools, transforms the buttons and external design of the browser into the feel of antiquity.

Representatives for Mozilla and HBO’s agency, Deep Focus, said it is the first commercial theme developed for Firefox.

“The browser is an important piece of real estate,” said Ian Schafer, CEO of Los Angeles-based Deep Focus. “This is one way to break through the clutter.”

It only confirms what I have been saying all the time. Branding & Promotion through browsers are great real-estate.
