But, the BBX mash-up explanations given above are the real reason for the jump from 7 to 10 AFAIK. It was all over these forums at the time. Someone in BB legal must have dropped the ball when it came to checking if that name was in use by another company.
@bobshine: there's a fairly straightforward explanation for that... you should maybe ask your parents to explain. Don't settle for the birds and bees explanation, which confused me for years. ;)
