Since its BBC Two debut last month 'Top of the Pops' ratings have plummeted to an all-time low of 1.1m viewers, down from 2.4m on BBC One a month earlier.
Corporation bosses made the decision to move the show from its primetime Friday night slot last November after ratings slipped to an average of 2.4m.
In its heyday in the 1970s, 'Top of the Pops' attracted audiences of more than 10m, hitting a peak of 19m viewers for a Thursday night show in 1979.
However, the move to BBC Two has also seen 'Top of the Pops' go for an older audience as elements of 'Top of the Pops 2' are integrated, with older songs being played.
Sunday night's episode was easily beaten by a Channel 4 screening of 'Carry On up the Khyber', BBC One's 'Antiques Roadshow', ITV's 'Emmerdale' and 1997 Herbie film 'The Love Bug', on Five, starring John Hannah.
A BBC spokeswoman said that viewing figures fluctuated across the board in the summer.
"For us, this is not a problem, but a sound transfer. We knew that 'Top of the Pops' would undergo a period of adjustment," she said.
The show first launched on BBC One in 1964 with Sir Jimmy Saville as presenter. It was famed for its mini-skirted dancers Pans People and catapulting bands such as The Beatles and The Rolling Stones into the public eye.
