Atari Buys Intellivision Brand, Ending ‘Longest-Running Console War in History’ [wasn't actually still running, but ok]
Atari acquired the brand of long-time rival Intellivision and the rights to more than 200 games from Intellivision Entertainment.
It wasn't an active war anymore, and Atari isn't Atari anymore. Idk about Intellivision, but I'm sure they've changed hands loads and diluted their brand too. Nothing burger "war" tastes of nothing
