Though to be fair, not under the Disney name itself. They intentionally set up the Touchstone label in the 80s so that their non-family content wouldn't be Disney branded- I'm pretty sure most people didn't even know Touchstone was Disney. It took until 2003 and Pirates Of The Carribean for anything with the Disney name to get a higher rating than PG (and until 1979 for them to even make anything PG!). And even then you could argue that Pirates still isn't that family unfriendly despite that.

Disney was still being ultra-sensitive with usage of their brand even later than that. When they owned Power Rangers (acquired by buying Fox Family Worldwide, which included Fox Family, Fox Kids and Saban Entertainment, the latter being PR's production company), they didn't include their name on the show at all like Saban did and like most Disney (and Nickelodeon) shows do. They initially credited it to BVS (Buena Vista Studios), and then to Jetix (the name Fox Kids had rebranded to). They disposed of the franchise in 2010 by selling it back to Haim Saban, in the same year the Jetix brand was scrapped (the channel was renamed Disney XD). Apparently they thought the martial arts was too violent to be associated with the Disney brand, even though, of course, the show is PG rated (on US TV it was TV Y7FV, which means suitable for over 7s and includes fantasy violence).
