Back in 2007/2012 our company was in flux and we didn't do many upgrades at all and we fell way behind in keeping upgrades going... had a lot of SQL2000 and 2005. Fast forward to 2013 till now and we are in much better shape as we are moving forward with upgrades at the IT budget level. I have also been prodding apps folks to upgrade, upgrade, upgrade as well which moves things along well. We had our last SQL2000 db in May 2014 and I have been actively moving everything off of SQL2005... we have two old apps still on it thought I must say... one is going to SAAS in June and the other is in parallel testing to SQL2012. I have been attempting to be ahead of the game with everything we have still in SQL2008 and 2008R2. Hope to be close to off of it before it goes completely out of support in 2019.
