Since then, the CEO of Placebase became a part of Apple's "Geo Team". In the following two years, Apple acquired two more mapping related companies who specialized in 3D maps: Poly9 in 2010 and C3 Technologies in 2011. C3 Technologies' imagery was later used for the Flyovers feature in Apple Maps. Earlier in 2011, Apple indicated its plan for a mapping service when it stated on its website that it was collecting location data to create "an improved traffic service in the next couple of years" for iPhone users. In September 2012, when Apple Maps was released, a source connected to both Google and Apple Maps claimed to technology website "TechCrunch" that Apple was recruiting Google employees that worked on Google Maps. In the first year after its release, Apple Maps received a number of improvements which solved various errors in the application. Other changes included adding more satellite imagery and making the navigation available in more cities. In 2013, Apple also acquired a few companies to improve Apple Maps, namely HopStop, Embark, WifiSlam, and Locationary, as well as the team and the technology of the company BroadMap. HopStop and Embark both specialized in mapping public transportation, WifiSlam specialized in interior maps, Locationary provided accurate company data for mapping services, and BroadMap managed, sorted, and analyzed map data. During WWDC in June 2013, Apple announced the new version of Apple Maps in iOS 7. This new version had a new look and icon. A number of new functions were also implemented, including full-screen mode, night mode, real-time traffic information, navigation for pedestrians, and the Frequent Locations feature. The latter feature, which can be switched on and off, was introduced to record the most frequently visited destinations by users in order to improve Apple Maps. In addition, new satellite imagery was added once again. On September 18, 2013, Apple released iOS 7. At that time, the new iPhone 5S included a new motion coprocessor, the M7, which can identify whether a user is walking or driving in order to adjust the navigation mode. During that same conference, Apple announced that a desktop version of the application would be made available for OS X Mavericks. On October 22, 2013, Apple released OS X Mavericks and the desktop version of Apple Maps. The desktop version was similar to that in iOS 7, but it connected with the Contacts and Calendar applications. Additionally, the desktop version enabled users to send locations and directions to other devices with iOS.
