50th Anniversary to Air in 3D

The BBC has announced that the 50th Anniversary of the show will air in 3D. With next to nobody having 3D television sets, this has sparked a lot of controversy among fans. Some have wondered, for instance, why they're spending money on this, rather than making the episode longer than 60 minutes. I personally see 3D as a gimmick. It has so little market penetration that there's almost no point in doing it, other than being able to claim you did.
