Producers William Bickley and Michael Warren have entered into a new long-term exclusive TV development and production deal with Lorimar TV, calling for their Bickley/Warren Prods. to create and produce all forms of television.

The arrangement also involves Bickley and Warren continuing as exec producers on the comedy series “Family Matters,””Step by Step” and “Getting By,” all of which they created and produce in association with Miller-Boyett Prods.

Both “Family Matters” and “Step by Step” were recently renewed for next season, occupying the 8 p.m. hour of ABC’s “TGIF” Friday comedy block (Daily Variety, April 1).

Bickley and Warren began their association on “Happy Days” and started at Lorimar in 1986 as exec producers on another Miller-Boyett comedy, “Perfect Strangers.”
