AT&T is allowed to buy Time Warner

Judge says yes to merger. I would venture that this decision bodes well for the possible T Mobile/Sprint merger.

Perhaps 'bodes well', but kind of an apple & oranges comparison.

AT&T centers more on vertical integration of content and distribution under control of a single entity.

T-Mobile/Sprint is centered more on straight issues of competition/cooperation.

Personally, I might guess that CNN not being involved in any way in the T-Mo Sprint merger probably has more effect on the chances of approval than the AT&T case does (on it's legal merits).
