Comcast-NBC day. The terms of the deal are more or less as expected: a 51/49 joint venture, $30 billion valuation for NBC U. All Things Digital liveblogs the conference call. The CEOs go on CNBC (video) to talk up the deal. Comcast issues a memo detailing the concessions it’s prepared to make to federal regulators to get the deal approved. The biggest surprise? Comcast says a premium Hulu tier is “not in the cards.” That should make for some interesting discussions with News Corp. at the next Hulu board meeting.
