You have a good domain with very specific niche .TV so there will be a narrow space to move, and autumn usually means less pleasure for many
The domain have potential for sure. But do people like autumn in general, will they like an autumn tv channel and what tv shows they will enjoy on it?
Well, not all sites are developed only for pleasure. ''Autumn'' symbolizes the maturity and adulthood, exacly the opposite of spring. It could be a site with autumn related music, or Halloween themes. These just the ideas.
