The BBC Children in Need Appeal raised over 18 million pounds on Friday, with £1.6m coming directly from BBC Radio 2.
The station's former breakfast presenter Terry Wogan hosted seven hours of live entertainment on BBC 1 TV, along with Radio 1's Fearne Cotton.
The money was raised by listeners bidding for various prizes, including the Weekend Wogan Auction, requesting a tune on the Music Marathon and joining Chris Evans for his Breakfast Dine and Disco weekend.
Wogan said: "The generosity of the Great British public is just staggering and we are so grateful for all your donations.We couldn't help the disadvantaged children and young people of this country without your help so please give what you can and help change a young life for the better. Thank you."
