How might the BBC be funded if the licence fee is scrapped?

Advertising. Subscriptions. A household levy. The government claims to be considering all options for funding the BBC. In reality, however, many industry insiders believe radical reforms will be dodged in favour of sticking to the licence fee model - perhaps for the last time.
