The cornershop comedy, starring Sir David Jason, returned to BBC1 on Boxing Day for a second series and according to figures, the latest episode last Sunday drew in 7 million viewers - one of the highest figures of the evening.
The channel's new War and Peace drama attracted 5.3 million viewers, the same as the Antiques Roadshow while Countryfile topped the list with 7.4m viewers.
ITV’s Inspector Morse prequel Endeavour drew in 5.1 million for its second episode.
The first series, screened early last year, saw nearly eight million viewers tune in for the final epsiode of the updated comedy show.
Viewing figures rose steadily across the course of the first series. The viewing figures for this year's run are similar - meaning that a third series could be commissioned.
The revival comes after a Christmas special from 2013 which proved to be the biggest hit of that year's festive programming.
That episode drew in more than 12 million viewers and became one of the most watched shows of 2013.
The original series of Open All Hours ran between 1973 and 1985 and starred Ronnie Barker as penny pinching shopkeeper Arkwright as well as Jason as put-upon errand boy Granville.
The new series sees Jason reprising Granville, who now runs the shop, with his son Leroy.
Outdoor scenes were filmed at the Beautique hair salon on the corner of Lister Avenue and Scarth Avenue in Balby last September - the setting for the original show.
