On April 1st, 2011, stunned viewers of the French TV channel Nolife discovered that the channel's daily show "101%" had been hacked by Razor 1911.
Yes, it was shown this way on TV, with the starting black screen simulating a broadcast crash :)
It was shown in three different versions (this is the second one with the fake NSFW review).
The intro also gave a "cracked" code that granted access to the whole replay service (Nolife Online) during one full day.
