Between its massive market share and rising subscription prices, Netflix is having to look for other ways to gain and retain viewers; one of the most talked-about is the possibility of an ad-supported tier. If you're used to watching your TV shows and movies offline, though, you may need to keep the more expensive, ad-free subscription, according to a report from Bloomberg.

Initially spotted by developer Steve Moser, code in Netflix's app indicates that offline downloads will not be available for those on Netflix's ad-supported tier, leaving the option as a perk for ad-free users.

Last month, Netflix said that the service's ad-supported tier or tiers might not include all content.
