In the wake of its initial popularity and corresponding increase in the number of screens, more films are being released in the 3D format. For instance, only 45% of the premiere weekend box office earnings of "Kung Fu Panda 2" came from 3D screenings as opposed to 60% for "Shrek Forever After" in 2010. In addition, the premiere of "Cars 2" opening weekend gross consisted of only 37% from 3D theatres. "Harry Potter and the Deathly Hallows – Part 2" and "" were major releases that achieved similar percentages: 43% and 40% respectively. In view of this trend, there has been box office analysis concluding the implementation of 3D presentation is apparently backfiring by discouraging people from going to film theatres at all. As Brandon Gray of Box Office Mojo notes, "In each case, 3D's more-money-from-fewer-people approach has simply led to less money from even fewer people." Parallel, the number of televisions sold with support for 3D television has dropped, let alone those sold with actual 3D goggles.
