I'm offering a 1000 BTC bounty for getting a major business to accept Bitcoins as payment. Conditions:

The business should have at least tens of thousands of customers and a revenue of at least 50 -100 million USD.
The business must accept Bitcoins as payment for the most of their services.
The business must provide a reasonably convenient way to pay with Bitcoins. If it's an internet business, they should process the Bitcoin payments automatically.
The bounty recipient(s) must prove that they convinced the business to start accepting Bitcoins. Contact Sirius by a PM or IRC when the business has shown interest in accepting Bitcoins.
The bounty will be paid when the business has accepted Bitcoins as payment for 3 months. If they accept Bitcoins for less than 3 months but at least 3 weeks, the bounty will be 200 BTC.
The bounty expires on 31.12.2011. The business must make the decision to try out Bitcoins before that.
These terms are subject to change.

Ask me if you're unsure if your business qualifies. Feel free to contribute to the bounty amount.

Suggestion: Try to get a poker site to accept BTC

Is this still up for grabs? :-)
