In 1994 he helped create the first animated late night talk show Space Ghost Coast to Coast for the Cartoon Network. Then in 1995, Lazzo's newly-named production company, Ghost Planet Industries, produced the first spin off from Space Ghost: Coast to Coast, Cartoon Planet which debuted on TBS, but later moved to Cartoon Network the following year.

Keith Crofford has served as Lazzo's co-executive producer since 1994.
