Season 1 of 水曜ドラマスペシャル premiered on October 17, 1984.

The origin of this slot is the Wednesday one-off drama "Love is a Mystery Theater," which aired from October 1984 to March 1986 . The program was retitled "Wednesday Drama Special" from April 1986 and continued broadcasting, ending in September 1987 .

the station's two-hour drama slot went on hiatus for six months, and in April 1988 , it was reorganized and moved to the " Saturday Drama Special " on Saturdays at 10:00 p.m. and 11:00 p.m.

From October 1989, the two-hour drama slot on Saturdays at 10pm and 11pm was renewed as " Dramatic 22 " , which inherited the concept of " Drama 23 ". In response to this, a new drama slot was established on Mondays at 9:00 pm and 10:00 pm to handle suspense, etc., which had been broadcast on "Saturday Drama Special" etc. [Note 1] . This is the first time in 20 years that TBS will have a two-hour domestic drama slot on Mondays, since the Akira Kurosawa series, which aired a drama film as a filler program from August to September 1969 .

The successor program will be " Monday Mystery Theater " → " Monday Golden " → " Monday Masterpiece Theater "), and the 2-hour drama slot ("-Golden" and "-Masterpiece Theater") will be aired in this time slot on TBS until March 2019. (Not limited to dramas) continued for 29 and a half years.
