In year 2014 we started to help to promote a serials of Android TV app international promotion, the first one is www.androidapp.tv;
it's China focused version is www.androidchina.tv;
a smaller scale focus is Shanghai www.androidshanghai.tv;
In the mean time we have added the lasted live TV Android app in satellite websites of both DishHD and Dream, links are www.dishhdtvchina.com/iptv/ & www.dreamsatellite.com/android/.
The online shopping cart project has not been moving forward as expected, we spend a lot of time and energy but it turned to be a silent one www.kiwiantennas.co.nz/shop/.
The Chinese version is not attracting enough sales leads as well www.kiwiantennas.co.nz/chinese/.

New projects will be added soon. I probably give up product sales, only to promote home repair and installation service and online app download and installations.
Ebay and paypal portals are under construction.
