Existing customers can get their hands on a free attachment to connect The Nation's favourite PVR is getting a refresh with the launch of two new boxes which will both have built-in Wi-Fi for the first time The Sky+HD and Sky+HD 2TB boxes will obviously aid access to Sky's On Demand service, which is currently enjoyed in 2.7 million homes and registering an average of 6.2 million downloads a week. The boxes connect wirelessly to a home Wi-Fi network with the touch of a couple of buttons. Once connected, customers can instantly access Sky's On Demand service, including up to the last 30 days of TV from the UK's biggest Catch Up TV service, the latest Box Sets, plus hundreds of movies from Sky Movies and Sky Store. And to ensure that all homes with Sky+HD boxes can get connected, existing customers who have not yet used On Demand can receive a free On Demand connector. This connector will allow them to connect their set-top box to their Wi-Fi network, giving them access to the additional entertainment. To check eligibility Sky customers can visit sky.com/connector. There's a lead time of 3 months for the connector and stocks are limited so we'd advise you sign up PDQ. Also, as noted below, if you've already used the on demand service via a wired solution, you won't qualify for the free device, which seems like a pretty poor state of affairs to us and penalising those who have already shown support for their OD platform. Sky customers with On Demand will receive up to 20 new channels on Catch Up TV over the next year. The first channels to be added to the service will include Discovery, Dave, Gold and Cartoon Network, all arriving before the end of the year. This Autumn, Sky will also continue to expand the number of TV Box Sets available. From September this will include Hannibal (Series 1, Sky Living), Friday Night Lights (Series 1 and 2, Sky Atlantic), Falling Skies (Series 1 and 2, Fox) and Rescue Me (Series 1-2, Sky Atlantic). Luke Bradley-Jones, Sky's Brand Director of TV Products, comments: "Record levels of On Demand viewing show that Sky customers love the flexibility the service offers. When people connect their Sky+HD box to broadband they get instant access to the UK's biggest Catch Up TV service and an extensive On Demand library of TV Box Sets and exclusive movies – and we're seeing a growing demand.
