Fey said that from then on "it became a thing where [they] tried to keep it going", and that even though they could not include one in every episode, they still had a "pretty high batting average". Fey attributed most of the references to Carlock, whom she described as "the resident expert". Reception According to the Nielsen Media Research, an average of 7.2 million viewers watched "Apollo, Apollo" during its original United States broadcast, placing it in third place for its timeslot. The show also claimed a 3.4 rating/8 share among viewers aged 18 to 49, meaning that 3.4 percent of all people in that group, and 8 percent of all people from that group watching television at the time, watched the episode. This was an increase from the previous episode, "The Bubble", which was watched by 7 million American viewers. "Apollo, Apollo" was generally, though not universally, well received among critics. Television columnist Alan Sepinwall for The Star-Ledger wrote that the episode was "easily the best 30 Rock of the season, and one of the series' best episodes to date".

Poniewozik said it "nailed it, from the too-many-good-jokes ... to the sweet heart at the center of each character." The A.V. Club's Nathan Rabin enjoyed Adam West's cameo, but noted that Tracy's plot "felt awfully shticky and sitcommy to me." He opined that "Apollo, Apollo" was "pretty great" for Jane Krakowski's Jenna, and in conclusion, Rabin said "I had initially pegged this episode as good but not great and essentially minor in the grand scheme of things but while writing this post I came to realize just how much of it I loved. 30 Rock is pretty great even when it's not that great." Rick Porter, a contributor for Zap2it, said he "loved" the episode, writing
