It didn't mean to, but it became popular so it was abused and now it's being over abused so now it's killing gaming since it's all about graphics and shooters and realism that costs too much and sells too little if it's not a big name brand.
So it did, but indirectly and didn't mean to.

I don't think it's a definitive yes, but I do think it has had some negative effects on the industry. However, these problems could be attributed to any game that initially did this, not necessarily Call of Duty specific. I think that being an annual series caused other developers to copy the formula and either create an annual series or to produce sequels in which there is almost no difference from the previous installment. I also think that it is also responsible for the dramatic inflation of game budgets with the expensive set pieces now shoehorned into games at the cost of gameplay/story.
So I don't think Call of Duty ruined gaming, but I do think it introduced bad habits into the industry that has spread like a virus to other studios and publishers.
