I saw this on a website listing Kosher soft drinks. I remember reading on some site that Teem was a short-lived lemon-lime Pepsi came up with in the 60's to compete with 7up. Is this stuff still available?

Teem was an attempt to enter that market back in the 50's, and it lasted up into the 80's in some markets, and died then, being at the time replaced by Slice Lemon Lime. Early competitor to the original Sprite as well. Pepsi has never had a legitimate lemon lime in the US, Slice Lemon Lime failed, Teem failed, then came Storm, and it failed, and now here's Sierra Mist, which in my opinion is doomed as well. Pepsi won't compete w/Sprite or 7Up, which the idiots dropped in some locales.
