Nine re-aired the Hey Hey By Request specials in 2005 and June 2006. Daryl and Nine agreed to a deal for two specials to air in late 2009. They aired in September and October and were a ratings success, attracting peak audiences of 2.64 and 3.1 million viewers respectively.

Premiering on 9 October 1971, Hey Hey It's Saturday was a Saturday morning children's program in which Somers and Carroll provided "top and tail" segments between cartoon episodes.

This was the final season before the show went into recess, when Daryl and Ossie took the bold step of leaving the Nine Network for the rival 0–10 Network to present a prime time show featuring 'comedy, audience participation and novelty games', simply titled The Daryl and Ossie Show.

Hey Hey It's Saturday returned to Channel Nine in 1979 after Daryl and Ossie hosted The Daryl and Ozzie show for rival The 0-10 Network the previous year. The show continued its evolution, beginning with the recruitment of popular Queensland TV presenter Jacki MacDonald as a co-host.

In 1984, the Nine Network moved the show from its morning timeslot to a primetime slot on Saturday nights, and it was briefly renamed Hey Hey It's Saturday Night before reverting to its original name. During this time, Hey Hey also became one of the most important TV venues for both local and international music, film and TV stars.

Nine Network executives decided toward the end of 1999 to cancel Hey Hey It's Saturday. Somers claimed that he wanted to take the program in a new direction after the departure of Caroll, but the budget to redevelop the show was deemed excessive. The final episode ran for 240 minutes, an hour longer than was scheduled.

Following the success of the 2009 reunion specials, the show returned in 2010 after a deal was signed for at least 20 new episodes. The show was set to air on Wednesday nights but retain the title Hey Hey It's Saturday with Daryl Somers returning as host. The show returned on 14 April 2010 with over 1.5 million viewers.
