We all know and felt the bomb explode when Microsoft dropped Halo on us as its first "Killer App" back on November 15, 2001 for the Xbox. But have we stopped to take a look and understand what effect Halo has had on the industry — especially its rival competitor, Sony?
First off, let's drop some quick stats for this Hall of Fame game:
| Milestone | Date | Figure |
|---|---|---|
| Halo: Combat Evolved breaks sales records | April 8, 2002 | 1 million units sold |
| Halo surpasses five million copies worldwide | November 9, 2005 | Over 5 million copies |
| Halo 2 worldwide sales (6.3 million in the US) | November 2008 | 8.46 million copies |
| Halo 3 first-week gross | September 2007 | $300 million |
Halo didn't just sell consoles — it redefined what a first-person shooter could be on a home console. Before Halo, the genre was largely considered a PC stronghold.

The "Halo Effect" became shorthand for the power of a single must-have title to shift the entire console landscape.
