It amazes me how much bigger TD could have been despite being one of the biggest eras in history
1)
Do a re-release, release a few new singles - March 2012
2) Then they could have done a remix album (the one where DJ's remix the songs) with like 2 new singles on it + a fam favourite demo. Release the singles. - Mid September 2012
3) Then an acoustic/Christmas album called "Teenage Christmas" (5 songs from TD + a cover, 6 Christmas songs) to get those holiday sales. Release like 3 Christmas songs in December. - Mid/late December 2012
4) Then then they could have done a remix album again (re-record and mix them again, this time adding a featured artist to every track). Add 4 new songs to it, release 3 singles, then release HH featuring T.I.
- March 2013
5) Release "Teenage Dream: 3rd Anniversary Edition" box set. Features Disk 1: Original TD, Disk 2: CC bonus tracks, Disk 3: Remixes Vol 1, Disk 4: Acoustic Christmas album, Disk 5: Remixes Vol 2, Disk 6: (A)Katy Perry, Disk 7: POM 3D - August 24, 2013
That is how you milk an album
It seems to have that effect...
