Reality is IMAX is not as popular as it once was either. They went from big screens to pseudo big screens squished into regular movie theaters – and then turned the volume up to +11. I have not watched an IMAX movie in an “IMAX theater” since The Hobbit came out – and the IMAX experience wasn’t much there, on one of the IMAX squished into a theater screens.
IMAX is now working on “IMAX VR” (which presumably includes 3D)
