MASTERCHEF On-Air Promos. Nik edited all the promos for the 72 episodes of MasterChef that aired between October and December 2010 on Mega Channel Greece. MasterChef swept the ratings across all age and gender groups averaging 35% share six days a week. Each on-air promo is presented unedited and in its entirety compiled in a larger video for each category: Beginning the episode (intro), going to break (coming-up) and previewing the following episode (outro). The language is in Greek with no English subtitles and the audio wasn't mixed by Nik.
