There's a whole slew of ex-TW companies that kept various parts of the name. It's kind of a mess, possibly deliberately.
As another example: the entertainment production company, Warner Bros., which produced both films and music, was acquired by Time Warner. Fast-forward some decades, and there are now two companies named Warner, one of which is part of TW and one of which isn't. The film part is still known as Warner Bros and is still owned by Time Warner. The music part, formerly known as Warner Bros Music, was renamed to Warner Music, and then recently (2011) sold off to some holding company, so despite still being branded as the Warner music arm, it's no longer owned by Time Warner, or related to the film part of Warner.
