Cherry Picking The Diamonds From The Stock Market

Do you know any blue chip stocks with stable long term dividend history?

I'm working on a valuation project and want to use the Discounted Dividend Model but I need to research a stock that has a stable dividend history in order for my assumptions to be valid. Any suggestions? Also, any expert advice on how long this dividend needs to be stable? 10 years, 20 years, more?
GE paid .1167 in 1998 and paid .31 in 2008 this doesn't seem stable to me…

Look @ GE or PG
