Time was SNL was a televised version of the National Lampoon Radio Show (the concept and cast were lifted in total).

The original cast mainly came from Chicago's "Second City".

Yes, they did. And they staged Lemmings (which was filmed for HBO and released as a record). And did the radio show, and the cast got scooped up for television.

Some Second City comedians went to Canada with SCTV in the late 70s/early 80s and it eventually was picked up in the US by NBC.

I haven’t heard of other ensemble success coming out of Second City. Some lone names before and after but not a peer group.
