Computer science got a nice boost of publicity when the contest started and a little bit less with the end, I think because of the big lag before the contest ended on July 26th and the final results announced yesterday. Still good to get some positive CS press after trading algorithms (and by consequence computer science) get some of the blame for the financial crisis.
Netflix got both publicity and nicer algorithms from the contest. So they will do it again this time with demographic and historical data.
Meanwhile P v. NP remains open.
