On November 14, the Official Singles Chart will be clocking up another No.1 when it celebrates its 70th birthday. It has seen artists like Elvis and the Beatles hold record positions.
The chart, which began in 1952, was the brainchild of Percy Dickins, who co-founded the NME that same year.
He could never have predicted that his chart of weekly record sales would still be going strong, 70 years later.
But what started as a snapshot of the favourite sounds of the time has changed dramatically over the years.
While the chart was first published in the NME, the launch of Top of the Pops on BBC1 in 1964 and Radio 1 in 1967 saw popular music consumed in new ways.
Then, the digital age and streaming launched another muscial bonanza.
Martin Talbot, chief executive of the Official Charts Company, says: “There’s more access to more music in different ways than there’s ever been.
“In the past, you’d hear a record you liked on the radio, then you’d go into your local record shop, ask if they had it and if they didn’t, you’d order it.
“The level of consumption we see now in a streaming environment is off the scale – and continues to grow.”
Martin says that today, the average No.1 single is streamed 7.4 million times in a week. To make the Top 10, you have to achieve around 2.9 million streams.
But Martin recalls: “Some of the biggest years for single sales were in 1978 and 1979. Then, there were 78 million singles sold in the UK, partly because of the growth of punk and disco coming together and because it was just a massive time for music.
“Then came the digital era. In 2012, 180 million singles were sold in the UK.
“We saw a doubling in the size of the singles market with the advent of downloading and that made accessing and buying music so easy. The digital revolution meant people could listen 24/7.”
But many older pop fans remember huddling around the radio to listen to the singles chart being counted down and long for the nostalgia of the past.
Martin says: “In the early 70s, people would say, buy a Slade record and then the following week, they’d see them on Top of the Pops if it went into the chart.
“The power of the charts and their social significance at this time can’t be underestimated.”
But while Top of the Pops ended in 2006 and the music lovers of today listen to the hits in many different ways, the Official Singles Chart – which is still broadcast on Radio 1 – lives on.
And the annual race for the Christmas No.1 is still just as exciting as it has always been.
Martin believes the singles chart will always be relevant.
He says: “Everyone involved in the creation of music is incredibly competitive. They want to be the biggest and the best. What better way to reflect that then through a weekly race?”
