What happened to the GE light bulbs?

I recently visited the light bulbs section at my local Lowes to buy replacement bulbs. I noticed that the GE light bulbs are all gone. Not just one type; all of them. All of the light bulbs are replaced by this company called “Utilitech,” which I’ve never heard before. I thought Lowes will be the only store with the GE light bulbs. What happened?
