Pottermore’s CEO Charlie Redmayne spoke with The bookseller on Pottermore to give an update on Pottermore, Chamber of Secrets and some stats as well.

On April 24th we learned the Chamber of Secrets was weeks away from launching in Pottermore, but today Redmayne is re-emphasizing that few weeks. They’re must have been a delay of some sort.

“Over the past two weeks we’ve seen sales settle down, but they remain very significant, and way beyond what we originally budgeted for.” He added that sales of the physical copies of the seven titles had also increased, and that because of the site’s light-touch Digital Rights Management, piracy had diminished.

“Obviously there were fears piracy would increase as a result of being DRM-free, and that sales of the e-books would cannibalize sales of the physical titles, but we were delighted to see sales of the physical books go up, and piracy come down.”

Pottermore, the Harry Potter experience, has seen 22m visits from 7m unique users in its first two weeks, generating more than 1bn page impressions, with the average user visiting 47 pages, spending 25 minutes on the site.

Redmayne said there had been 4.2m attempts to make potions, with a success rate of just 32%. In those first two weeks there had been 39.9m “wizard duels” with the “full body bind” spell the most popular, and “pimple jinx” the least used. He said that after two weeks 5m new users had registered, with perhaps half of those already sorted into houses, such as Gryffindor and Ravenclaw.
