For most of "TGIF"s run until the 1998–99 season, at least one series on the lineup was produced (and in some cases, developed) by the team of Thomas L. Miller and Robert L. Boyett, whose relationship with ABC traces back to the premiere of "Love, American Style" – produced by Miller and former producing partner Edward K. Milkis under a development deal with Paramount Television – in 1972. The first two series were "Perfect Strangers" and "Full House", both of which were produced through Miller-Boyett's development deal with Lorimar Television and aired on the network's Friday night schedule prior to the launch of "TGIF". (The latter premiered in September 1987 as part of the network's Friday schedule, while the former concurrently was moved from Wednesdays to Fridays that month.) In September 1989, "Family Matters" – a spin-off of "Perfect Strangers" originally centered solely on the family of Harriette Winslow, who began as a recurring character on its parent series, before becoming centered increasingly around the breakout character of Steve Urkel starting with its second season – joined the lineup.
