Sony yielded to crackpot internet-threats and cancelled the Christmas Day release of their new comedy film The Interview. Whilst North Korea hasn't publicly accepted responsibility for those threats, it doesn't take a genius-level IQ to spot that the single biggest beneficiary from this cancellation is dictator Kim Jong Un.
Comedy calls-out the corrupt. If you attack them with sanctions then they'll use those sanctions to rally the masses -- just look at Russia's Putin who is enjoying sky-high popularity despite a plunging economy. Attack them with laughter however, and the despotic have nowhere to hide.
