Three familiar faces were missing from the family outing. Prince William is spending the holiday with his pregnant wife Kate and his in-laws in the southern England village of Bucklebury. Prince Harry is serving with British troops in Afghanistan.

After the church service, the royals usually gather to watch the queen's prerecorded television broadcast, a tradition that began with a radio address by King George V in 1932.

The queen has made a prerecorded Christmas broadcast on radio since 1952 and on television since 1957. She writes the speeches herself and the broadcasts mark the rare occasion on which the queen voices her own opinion without government consultation.

Her switch to 3D was not the only technological leap for prominent British figures this Christmas.

The Archbishops of Canterbury and York chose to tweet their sermons for the first time, in order to bring Christmas to a new digital audience.

In his speech, Archbishop of Canterbury Rowan Williams said he has been inspired by meeting victims of suffering over the past decade while leading the world's 80 million-strong Anglican Communion.

Delivering his final Christmas Day sermon from Canterbury Cathedral, Williams also acknowledged how a vote against allowing women to become bishops has damaged the credibility of the church.

Still, he said, it was "startling" to see after the vote how many people "turned out to have a sort of investment in the church, a desire to see the church looking credible and a real sense of loss when — as they saw it — the church failed to sort its business out."
