Hold up there bubba. 4e was perhaps not as popular as 3.5, but it was still popular. It didn't drop D&D off the charts or turn it into an unknown game.
Something being "not as popular as this other thing" does not translate to something being "not popular".
Right. Shadowrun, Vampire, Cyberpunk, Call of Cthulhu, Rifts, and many more were never as popular as any given edition of D&D, but they were still quite popular.
