Last weekend Blizzard hosted their latest open beta for the new Diablo III game in order to stress test their services building up to the games release on May 15th, and have now released a tv spot ad to advertise the game, which they explained with this description:

The Lord of Terror has begun his demonic crusade to shackle YouTube viewers into unholy slavery. Watch our new TV spot now, and prepare for your journey into the depths of Sanctuary on 05.15.12.

You can pre-order the game today from here, and check out the ad above.
