Verizon is looking to close the doors on its app store this coming January. Originally set up in March 2010, the market served as an alternative source for Android and BlackBerry apps for Verizon devices. The store is better known as Vcast Apps and will hopefully be removed from all customer devices by March 27, 2013.
Verizon has recognized that times have changed and that it's pretty pointless for them to be hosting their own app store when Google does such a great job with Google Play and BlackBerry is now pushing apps on its new devices. The majority of the apps that have been available in the Vcast app store are available through other sources.
Verizon, along with other carriers, would like to provide apps that are specific to the network as it gives them a little something extra to bring customers over from competitors. These custom apps would include providing things specific to a single network, such as carrier billing or other carrier-specific features.
