The Entertainment Retailers Association (ERA) has thrown its support behind MCV's Digital Counts campaign.
The trade body says it estimates that games' digital market is bigger than both music and video, but is unable to say definitively due to the lack of tracked figures.
In a letter sent to MCV, chief executive Kim Bayley and the Board of ERA said:
Our longstanding commitment to open data is reaffirmed every week with the publication of the GfK Chart-Track charts, based on data provided by our members,” it read.
We have been working behind the scenes to encourage more openness about digital data, and remain hopeful that this can be achieved.
The digital games business has been a huge success. Our estimates suggest that it is bigger than digital music and digital video put together. It is as a result of the success of digital games that the games sector overall has overtaken video to become the biggest of the three entertainment categories in which our members operate.
That success story deserves to be told.”
