Originally started as an app long ago back in 2013 Sony’s TV SideView was a very interesting application. Sadly come May 24th it’s going to be departing. The following statement is from Sony’s product site.

Thank you very much for your loyal support in using Video & TV SideView.
TV Programs and Video on Demand functionality will no longer be offered on Video & TV SideView from May 24th, 2017.
Functions that will no longer be offered:
– Program guide
– Top picks（excluding My Library for Android）
– Timer REC
– Reminder
– Bookmark
– SerialAbTak, YouTube, PlayStation Video, Crackle, watchmi, UseeTV, PPTV, Zattoo

Please note that the following functions will remain available:
Remote control, Home network, My Library(only for Android), Mobile device(only for Android)

*Some functions and services may not be supported in certain regions/countries

As you can tell this is out of the blue and some Sony TV users won’t be happy about this. But at the same time many users by the looks of it never knew of the application existed. Farewell Sideview and lets hope you have a replacement someday.
