Media Culpa is an interesting media blog which also includes following Flickr. Since I use Flickr in lectures I find this very helpful. Here is the latest on Flickr growth from Media Culpa.
On May 17, 2008, the 2,500,000,000th photo was uploaded to Flickr (photo here). If we look at previous milestones, it appears that the growth of Flickr could be slowing down. In November last year I wrote that the first billion photos took three and a half years while the second billion took three months. Now we can assume that it took six months to get the next half a billion photos.
I have compiled the graph below out of data directly from Flickr by checking a series of photos to find the date they were uploaded and hopefully they are correct. Regarding the growth, we know that much of the explosive increase during mid 2007 (from June and three months forward) was due to the migration of photos from Yahoo Photos. But despite the fact that Yahoo Photos supposedly had 2 billion photos, the figures suggest that far less than 1 billion were migrated into Flickr.
So, while I don’t have any official figures from Flickr, it does not seem that the organic growth is keeping the same pace as it did in the fall last year. It will be interesting to keep an eye on the development the coming six months for Flickr.
Footnote: The series of data I used was the following:
