"SpongeBob Every Day on Nickelodeon" shows old episodes in the promo. It was normally shown on Nickelodeon CEE, Nickelodeon Europe HD and Nicktoons Global from season 5 of SpongeBob. Seasons before season 5 wouldn't show unless it was Christmas or a special block. I think the seasons before season 5 will also show all nick channels (Nickelodeon CEE, Nickelodeon Europe HD and possibly Nicktoons Global).
