TRL meaning in Community ?

Total Request Live (known commonly as TRL) was an American television program broadcast on MTV that premiered on September 14, 1998. The series featured popular music videos played during its countdown, and was also used as a promotion tool by musicians, actors, and other celebrities to promote their newest works to the show's target teen demographic.

During the original run of the program, TRL played the ten most requested music videos of the day, as voted by viewers via phone or online. The show generally aired Monday through Thursday for one hour, though the scheduling and length of the show fluctuated over the years. Although TRL was billed as a live show, many episodes were actually pre-recorded. Due to declining ratings, and the larger secular decline of music-based television in favor of online services, MTV would announce the cancellation of TRL on September 15, 2008. The special three-hour finale episode, Total Finale Live, aired on November 16, 2008.

Less than a decade later, TRL would be revived on October 2, 2017. In 2019, the show aired Saturday mornings at 10am ET as TRL Top 10. The show was then rebranded to Fresh Out Live.
