Science magazine's Best of "What's New 2009". At the time, it was the largest load-bearing glass structure in the world, designed by engineers at Dewhurst Macfarlane using a plastic film called SentryGlas Plus from DuPont. Controversy and the 50% off claims The TKTS booth, theater development fund, and Broadway show producers have been criticized for their claimed 50% off ticket prices. The prevailing belief is that TKTS offers 50% off of the normal sale price of a ticket, when in fact, those tickets are often subject to markups through a practice called "Dynamic Pricing". As Broadway producer Ken Davenport states in multiple articles and seminars, dynamic pricing is applied in theaters to help a show get more money for a seat. There have also been several documented case studies where a ticket found at the theater at full price for $89 to Kinky Boots, which is a Ken Davenport production, were sold at the TKTS booth at "50% off" for $75 plus the $5 TDF Fee. The same case studies found similar incidents at Chicago, Phantom of the Opera, and Jersey Boys. London London's TKTS, originally known as "The Half Price Ticket Booth", is run by the Society of London Theatre on behalf of the theatre industry. Operating since 1980 in the heart of Leicester Square, this discounted ticket booth offers customers a wide choice of discount theatre tickets on the day of the performance and in advance. There are also full price tickets regularly available through the booth. Tickets can only be bought from TKTS in person. Each TKTS ticket includes a booking fee of £3 on discount theatre tickets and £1 on full price tickets. All profits made from SOLT, including TKTS, go straight back into the industry. TKTS is also accredited by the Society of Ticket Agents and Retailers (STAR) and all ticket sales are made following the STAR code of practice. The Society of London Theatre has licensed the TKTS trademark from the Theatre Development Fund, but the two organizations are otherwise unrelated.
