What's the difference between Sky Anytime and Sky Anytime+?
Once you are connected to Sky Anytime+ you instantly notice the new programme images within the Showcase tabs which are exclusive to Sky Anytime+. Sky Anytime+ gives customers with Sky Broadband Unlimited* access to a huge library of TV on demand (content depends on your Sky TV subscription) delivered through their Sky Broadband service. The images show the difference in screens when connected to Sky Anytime or Sky Anytime+.
If you do not have Sky Broadband, then if you have a Sky+HD box or Sky+ you will see Sky Anytime which gives you a selection of the latest TV on demand (content depends on your Sky TV subscription) to discover whenever you want to. Every day we push programmes to your Sky box so you can watch them whenever you want.
Customers with Sky Anytime+ still have access to these programmes through the Showcase section of the service – you do not need to download anything from here as programmes are stored locally on your Sky+HD or Sky+ box. Everything else you will need to download, but remember if you are on Sky Broadband Everyday Lite, you have a download usage allowance of 2GB per month which means you could download approximately three 30-minute shows in SD (standard definition) per month along with typical general internet usage. If you want the freedom to download as much as you like then we recommend Sky Broadband Unlimited which has no usage caps.
*You can still access content with Sky Broadband Everyday Lite, but what you can watch will be limited by your 2GB monthly download allowance.
