The ticket price rise was steady but measured until the last decade. The upwards curve really starts to spike around 2007 - the peak of the real estate bubble. It then exponentially jumps in the new Yankee Stadium; despite the large decrease in 2010.
This spike is so large that on the graph, the top prices from 1967 ($3.50) to 1997 ($35.00) look nearly indistinguishable, because so much of the graph's real estate has to allow for the top prices of the last few years.
It took 13 years for the top ticket prices from 1967 to double to $7.00, and another 13 years to approximately double to $14.50 in 1992. After that, the intervals of when the top prices approximately doubled became much smaller, as you can see:
- 1967: $3.50
- 1979: $7.00
- 1992: $14.50
- 1997: $35.00
- 2003: $72.00
- 2007: $150
- 2009: $2500
