The difference between this and all the other censuses is that the 1911 census was never microfilmed. This meant that to put all the other censuses online, the genealogy companies would purchase copies of the orginal microfilms, then digitise, transcribe and index what they contained. The 1911 census only existed in paper form, which means that Brightsolid (owners of FindMyPast, amongst others) have had to photograph the original returns individually, digitise them, pay people to transcribe and index them, and make them available online. Any other companies wishing to host the 1911 census on their sites will have to purchase the digitised photos, and then do their own transcriptions and indexing. It's very unlikely that the National Archives will allow others access to the original documents, so companies will have to negotiate with Brightsolid for pricing.
