Traditional media's use of APIs for promotional purposes is picking-up lately. Mike Pegg has been highlighting a few new Google Maps examples over at Google Maps Mania. The two most notable ones, now added to the mashup listings here are the Sopranos Google Maps mashup from HBO and the NBC's Apprentice Cast Map from Virender Ajmani.
The Apprentice mashup is an example of how you don't have to be associated with a show or its PR to make a good mashup. Other recent examples include the Geography of Seinfeld and the Jacktracker for the show "24". (As a side note: the Jacktracker map was built at Wayfaring.com, a good community mapping site that helps simplify and enhance the process of creating a Google Maps mashup.)
The Sopranos map is quite slick with a Flash-based navigation and movie clips integrated into the map itself (again via Flash).
HBO has clearly put some time and money into the Sopranos mashup. How long until 'Google Maps Mashup' becomes just another PR campaign line-item in television and film circles?
