Grab a Kleenex and shed a tear. This is the upsetting page where you can see all the titles removed from Now TV since I started the service in April 2014. You can filter by genre and order by year or alphabetically. It will also show how long the title was available for on Now TV (where known) and, if you hover over the dates, you will see the exact dates they were added and removed.
Please note that if a title has been made available to stream again then it will not show up on this page.
