The ps4 is in the process of creating more history.
According to vgchartz the PSP sold an impressive 80.8m units and the GBA 81m units. The ps4 has now surpassed those to become the 8th best selling console of all time.
The ps4 has now shipped 82.2m. In the next few months it will take out the 360 and then the ps3 to become the 6th best selling of all time. Next year it will target the Wii and ps1 to become the 4th best seller. Finally I think it takes the GB at 120m and will sit comfortably as the 3rd best selling console ever but the 2nd best selling traditional home console after the ps2.
