The Official Charts Company has revealed an odd statistic for last year through their Twitter account.

According to them, the sales of cassette singles tripled last year.

Cassette format enthusiasts shouldn't expect a major revival any time soon though as the total number sold was 604; still a rather impressive number though.

"#OfficialChartFact: Sales of cassette singles, yes CASSETTE SINGLES, tripled in 2012 to ermm 604 units. Guess what the biggest seller was?"

"Two of you have guessed Mr Blobby. WRONG! Guess again.

"Neither was it Lisa Scott-Lee's - TOO FAR GONE.
