Culture minister Ed Vaizey discusses digital radio (DAB) rollout, the impact of second-screen viewing on conventional TV, the role of social media, video on demand and internet regulation

Culture minister Ed Vaizey is talking this morning at the Future of Entertainment Summit being held in London.

The summit – chaired by the BBC's technology correspondent Rory Cellan-Jones – is covering a wide range of topics, from digital radio (DAB) rollout, the impact of second-screen viewing on conventional TV, the impact of social media, video on demand and internet regulation.

Here are some of the key points mentioned so far:

• MP Ed Vaizey says " Digital radio switchover is going well: listening is increasing and in-car is at a tipping point. The majority of new cars will have DAB fitted as standard."

He also says "we met with electrical retailers and told them it's wrong to sell a customer just an FM radio; they will want a DAB option too".

Sky Now online TV service will launch in the summer, starting with films and then adding sport and entertainment later.

• Alex Green of BT says " YouView will shake up TV and appeal to people who have resisted pay TV so far".

• Ed Vaizey on the slow rollout of 4G :" If you want to know who to blame for 4G delay, ask the networks who keep suing Ofcom."

• Vaizey also says: "The rise of smart TV will create challenges for the tech industry when it comes to regulating content and protecting consumers."

• Vaizey confirms the Communications White Paper is due in early 2013, and will cover media ownership and plurality.

• Social TV will be worth $8-12bn by 2020.

• 70% of tablet owners use them while watching TV.

• Bandwidth demand from ISPs is up 40% year-on-year.

• Dan Saunders, Samsung: "We're trying to understand how consumers interact with Facebook and Twitter, while watching TV."

Ultraviolet – the 'digital locker' cloud service for storing and watching your film or TV collection anytime and on any device – should have two or three UK retailers by the end of this year, according to Gerald Hensley, vice-president of Rovi.

• Jim Bottoms of Eurosource says €121bn was spent on consumer entertainment in Europe last year.

On 3D TV, he adds "3D is a disappointment for everybody – it's a theatrical business, not a home one. Glasses-free 3D TV is still three to four years away."

• Jim Bottoms: "The biggest challenge is to keep the consumer paying for content."

• Rob Salter, Tesco: "Customers are getting more cautious about the entertainment products they buy." And he also believes Ultraviolet digital locker is too complicated for consumers to understand.

• In-store film purchases at Tesco will automatically be added to customers' Blinkbox accounts. "We need to offer complete solutions, rather than just products."
