LEGO

LEGO®, sometimes spelled Lego, was a children's building product that produced plastic bricks in sets, as well as little toy men called "LEGO Minifigures™". They didn't have LEGO sets during many elder's youth. Often, most children thought that LEGO was for boys only, while girls liked building hairdressers and flower shops. He built a ship to go to Mars, and then a bigger one to go to Jupiter the next week, before the Eighth Doctor and companions materialised the TARDIS in their sitting room. (AUDIO: Memory Lane) Space-themed sets were produced in Ace's time as well, who crashed spaceships into LEGO Police stations in her early youth. (PROSE: Set Piece)

LEGO Minifigures were much, if not minuscule in comparison to their real life counterparts. (PROSE: History 101) In fact, all LEGO models were significantly smaller than their real world equivalents. According to the Eighth Doctor, Toronto in the summer looked like "a giant LEGO set" from above the CN Tower. (PROSE: Trading Futures) Joseph similarly compared the skycrapers of New York to 'LEGO buildings' when atop the Empire State Building. (PROSE: Salvation)

The Savant, a great alien hacker of both computers and the human brain, enjoyed both eating LEGO as a snack, and bathing in it. Sarah Swann dubbed him "a hormone-secreting, LEGO-obsessed Sesame Street monster". (PROSE: Blue Box)

Bernice Summerfield at some point did an archaeological dig in an Earth LEGOland. (PROSE: Nobody's Children) She frequently had dreams of a bearded villain turning her into LEGO. (PROSE: Beige Planet Mars)

The Eleventh Doctor kept a LEGO room in his TARDIS. (COMIC: Sky Jacks)

According to Toshiko Sato, the two halves of a quantum transducer fit together like LEGO Bricks. (TV: Ghost Machine) Incopolis' streets were filled with buildings to similar in design that they looked like "they'd all been assembled from the same LEGO kit". (PROSE: Seeing I)

Liz Shaw compared the Seventh Doctor sifting through laboratory equipment to a child receiving a new LEGO set. (PROSE: Blood Heat)

Behind the scenes
Although LEGO initially could not produce Doctor Who sets to due licensing issues — and Character Options already making similar products —, a website where users get to vote on potential future products, accepted DW submissions in February 2014. This means that there is no longer a licensing conflict. A Who project attained 10,000 supporters on 13 March 2014, and therefore entered the review phase.

Arthur Parsons, of TT Games, stated in 2011 that he and the team would love to add LEGO Doctor Who: The Video Game to the list of of their design, should LEGO begin manufacturing Doctor Who sets.
