Sir Terry Wogan has departed Radio 2 breakfast with a set of figures to be proud of, pulling in 8.1mlisteners in his final quarter on the show to match his previous record.

And listeners to the final Wake Up To Wogan will be re-united with the presenter on Radio 2 on Valentines day, as he starts his new two hour show from the Radio Theatre.

Tim Davie, Director of BBC Audio and Music, said “Terry is a legendary broadcaster and these figures show his popularity has never been higher. I’m now looking forward to tuning into his new show later this month.”

Sir Terry’s performance at breakfast helped to boost Radio 2’s weekly share to 16.5 percent, matching the network’s record high, despite a slight decline on reach from 13.62m to 13.46m.

Over at Radio 1, the stations reach and share dipped a little, to 10.76m weekly listeners and a new share of 9.9 per cent, however the reach is an improvement on last year’s figures. The Chris Moyles Breakfast show has enjoyed a lift in reach with 7.24m listeners now tuning in each week.

Radio 3 has lost 320,000 listeners in the last quarter, giving the station a new weekly reach of 1.87m and taking their share down to 1.1 percent.

Radio 4’s previous quarter seen them hit a record reach of 10.21m, it’s now back down to 9.84m but the share has climbed a little to match the network’s joint highest figure of 12.5percent.

BBC Radio 5 Live and Sports Extra now have a combined weekly audience of 6.19m, with Sports Extra contributing 663,000 of that figure. The reach is better than that of one year ago but lower than last years numbers. Share has also taken a tumble to 4.6percent.

The BBC’s digital services have also performed well, with BBC 6 Music growing their audience to 695,000, beating figures for the previous quarter and year. BBC Radio 7 is now posting an increased audience of 931,000 while BBC Asian Network and 1Xtra staying steady with audiences of 360,000 and 531,000 respectively.

BBC World Service now has a reach of 1.23m.

It's all change in London for the top three commercial radio stations, as Global takes the top two positions for number of listeners for the first time for Heart and Capital under their new owners.

Bauer Media's Magic 105.4 drops to 3rd place behind Capital FM at two and Heart 106.2 on top, for the first time in almost three years.

However, if you calculate your success by share, Magic remains on top with 6.1, and LBC enjoys the longest commercial hours at 13.6 (compared to Heart's 5.3 and Capital's 4.9).

There's not much in the numbers though, as Heart is now listened to by 1.881million, compared to Capital's 1.827 and Magic's 1.821.

Kiss is not far behind with 1.605million, whilst LBC takes 5th place with 841,000.

Elsewhere, LBC News 1152 has lost almost 150,000 listeners this quarter, and GMG's Smooth Radio loses over a quarter of its listenership dropping from 583,000 to 414,000.

Global's Ashley Tabor, Founder and Group CEO said: “This is a landmark day for Global Radio, taking the Number 1 and 2 positions in London! It’s a target that the whole team here has been working to for some time and I’m delighted the hard work has paid off.”

Richard Park, Director of Broadcasting at Global Radio said: “We have worked hard to consolidate and re-structure our brands and today’s results show our ongoing commitment is paying off. We’re absolutely delighted.”

Steve Parkinson, MD of Bauer Radio London said: “I’m especially pleased that Magic’s share is number one again."

An IAB study, in partnership with Opinion Matters, surveyed 80 senior marketers and found that 88% of brands rate social media as important to their business. A third of advertisers planned to allocate between 6% and 20% of their digital marketing budgets to it this year, compared with just 14% last year.

However, there’s still great uncertainty about which department should be responsible for social media in the business. While three-quarters of respondents (73%) said social media should come under the marketing department, it was also found to be the responsibility of PR (33%), customer services (16%), research (12%) and IT teams (7%).

The biggest issue for social media is ROI, due to its qualitative nature. 74% of respondents believed that proving ROI was the greatest challenge for the social media sector. Measurement was viewed as the major stumbling block by 64%, while 57% said that more education about how to best use social media is necessary

Only 7% of respondents haven’t embraced social media in any way, but only 22% have interwoven it into core communications strategy. Of respondents, 20% feature social media in the majority of campaigns, while 23.5% opt to use the medium ad hoc and 27% have tested it with a view to using it again.
