Sir Terry and Moyles were neck and neck over the previous quarter
BBC Radio 2's Wake up to Wogan is the UK's most popular breakfast radio show, according to new figures from industry body Rajar.
Figures for the first three months of 2009 suggested Radio 1 presenter Chris Moyles might be gaining on his rival.
But new data shows 7.93 million people tuned in Sir Terry each week, compared with 7.72 million who prefer Moyles.
Elsewhere, BBC Radio 3 has reason to celebrate after achieving its biggest audience for more than two years.
A total of 2.02 million people tuned in each week during the last measurement period of 30 March to 28 June.
Rajar figures also show BBC Radio 4's audience now stands at almost 10 million after attracting around 465,000 new listeners in the past year.
But its flagship Today programme saw a slight fall in its weekly audience, its current reach of 6.51 million down on the 6.69 million posted last quarter.
Sir Terry and Moyles were almost neck and neck in the last set of quarterly figures, with the Radio 2 presenter ahead by around 80,000 listeners.
The veteran broadcaster's lead is now more significant, having attracted more than 200,000 additional listeners to his regular morning broadcast.
Elsewhere, BBC Radio 5 live has increased its audience by over 400,000 to its highest level since 2004.
In the commercial sector, Classic FM saw its audience rise by more than 300,000 over the past three months to just over 5.7 million.
The figures show that more than 90% of the UK population aged 15 and over tune in to their favourite radio station for at least five minutes in the course of a normal week.
