Kalyeserye was a soap opera parody segment that was aired live on the Filipino noontime variety show Eat Bulaga!

The show-within-a-show, as it had evolved, focused on AlDub, the fictional couple pairing of Alden Richards and Maine Mendoza's "Yaya Dub" character in which the two only communicate through lip-syncing to various pop songs and movie audio clips as well as written messages, and interact only on the show's split-screen frame.

The show featured live improvisation from Alden Richards, Maine Mendoza, Wally Bayola, Jose Manalo and Paolo Ballesteros, who all played various roles while the other hosts of Eat Bulaga!

The portion proved to be a success in both television and social media, resulting in a significant increase in viewership and popularity of Eat Bulaga!.

The appearance of other characters like the luxurious Frankie Arenolli (from the word arinola, "chamber pot") (Manalo) and the socialite DuhRizz (Bayola) make things even more complicated for the amorous pair.

[8] A month later, Maine Mendoza, who had initially gained online popularity by posting her Dubsmash videos in various social media platforms, auditioned for the program after catching the attention of its producers.

However, the Kalyeserye segment officially started on July 16, 2015, when Yaya Dub sees Alden for the first time.Day 1 On the episode broadcast July 16, 2015 (retroactively referred to as "Day 1"),[11] performed in Olongapo, Zambales,[10] Mendoza broke out of her "Yaya Dub" character when she accidentally smiled after noticing Alden Richards watching her on the show's live split screen.

Upon seeing Mendoza's spontaneous reaction, the studio panel members Allan K. and Joey de Leon teased the pair and thus prompted the producers to make an on-screen couple of the two.

[9][11] Mike Tuviera, a resident director of the show, revealed that the resulting "love team", christened "AlDub", was formed by accident because of the pair's natural on-screen chemistry.

[1] Pegged as Kalyeserye, it was characterized as a dramedy series with elements of parody of Philippine television drama, romantic comedy and reality TV performed by improv acting, broadcast live from the streets of different towns and cities.

[13] Some of the running gags and gimmicks throughout the parody series include a special gesture between Alden and Yaya Dub, called the Pabebe Wave.

[17] The Kalyeserye's main storyline is the Cinderella-like forbidden courtship between the AlDub tandem, with its paramount goal being the first physical meeting of the two, a move continually opposed by Lola Nidora.

In the show's August 8, 2015 episode, which featured the first wedding between the "YaKie" tandem, Mendoza collapsed unexpectedly while performing on live television and was immediately rushed to a nearby hospital, resulting in an improvisation by the segment's remaining characters — Frankie (Manalo), Lola Nidora (Bayola) and Alden himself.

[21] In its August 12, 2015 episode, Yaya Dub appeared at Broadway Centrum's TAPE Eastside Studio for her Cinderella-themed performance on Eat Bulaga!

The episode marked as the closest rendezvous between the two, only to be interrupted by Lola Nidora, who played as an evil witch and forced Yaya Dub to leave in the middle of her performance.

Approximately 55,000 people gathered at the Philippine Arena in Bocaue, Bulacan to witness the most awaited meeting of Alden and Yaya Dub; the couple was able to see and interact with each other without any hindrance from Lola Nidora.

On October 22, 2016, two days before the anniversary of Sa Tamang Panahon, the wedding of AlDub took place at the Shrine of Jesus the Divine Word in Quezon City.

The most used songs for their lip-synch interaction include "God Gave Me You" by Bryan White, "Thinking Out Loud" by Ed Sheeran, "Twerk It Like Miley" by Brandon Beal, and "Fantastic Baby" by Big Bang.

Towards the end in most of the episodes of Kalyeserye, the three sisters posed a la Charlie's Angels with "Wannabe" by Spice Girls being played in the background.

[52][53] According to AGB Nielsen's research, the August 12, 2015 episode marked the first time that the show reached the all-time high in viewership for the year with a 36.1% rating, which was mainly alluded to the tandem's near-meeting.

"[61] Anthropologist Anna Leah Sarabia cited the use of fairy tale and soap opera tropes contributed to the tandem's increasing popularity, saying, "It's a 'Cinderella' story that's fake and true-life at the same time.

[63] The popularity of the tandem even reached some schools and became a topic discussed in classrooms; for instance in a University of the Philippines Diliman Filipino class.

[66] The August 22, 2015 episode earned positive feedback from Catholic Bishops' Conference of the Philippines (CBCP) and Radyo Veritas via Twitter for highlighting Filipino love, responsibility and marriage moral standards.

This amount, which was achieved in one day, exceeded the number of Tweets sent with the hashtag #PapalVisit, during Pope Francis's January 2015 visit in the Philippines, a predominantly Catholic nation.

Kalyeserye helped Richards secure a four-year film contract with APT Entertainment, while the Philippine Basketball Association team Barangay Ginebra San Miguel and Mahindra Enforcers was also reported to have been considering inviting Mendoza as their muse for the 2015–16 PBA season, but she refused.

[71][72] Mendoza and Richards also appeared in separate profile interviews regarding the AlDub's success on the television program Kapuso Mo, Jessica Soho.

[75] In an interview with the celebrity talk show Startalk, Richards revealed that he did not expect the success of the show/segment and was overwhelmed by the popularity of the AlDub tandem.
