A stretch of time in popular music where modern Rock bands reduce guitar use in their music in favor of keyboards and electronics. Usually lasts about 3-5 years. This does not mean guitar oriented music doesn't receive radio airplay or that the bands in question remove the instrument from their music altogether.
The time this definition was written could be considered a dead guitar era, with the rise in prominence of bands like Imagine Dragons.
