On a related note, eGG Network is not the only channel on Astro that will be taken off the air soon though. There are other channels too including National Geographic, Nat Geo Wild, Ta-Daa and Boomerang that will be discontinued on 1 February although the pay-TV operator has already added new channels such as Global Trekker, Love Nature/Love Nature 4K, DreamWorks, and BBC's Cbeebies to become their replacements.
