This Classic Series Only Became Iconic When It Switched Genres Three Seasons In

by

MASH started as a little-known comedy, but it became hugely popular by doing something different with the sitcom format. Even today, over 40 years later, its final episode in 1983 remains the most-watched TV show of all time. This shows just how beloved it was, especially considering it aired before the days of the internet, streaming services, or even DVDs.

It’s surprising to learn that MASH almost didn’t make it past its first season. Initial ratings were very poor, and the show was only saved by being repeated. Fortunately, it quickly gained popularity, becoming a must-watch program that was both hilarious and deeply moving.

MASH was innovative in how it mixed humor with serious moments. While initially presented as an anti-war series, the first few seasons were mostly comedic. Over its 11 seasons, especially as Alan Alda gained more influence, the show shifted towards being a more traditional medical drama.

Similar to many successful TV shows, MASH didn’t immediately hit its stride. While the first season was enjoyable, it was inconsistent. The show truly began to shine starting with the second season. However, it wasn’t until the surprising season three finale – when it shifted from a purely comedic show to one that blended comedy and drama – that MASH became a beloved classic.

MASH Evolution From Sitcom To Dramedy Was Natural

Early 1970s television was generally much milder than today’s programming. Shows rarely featured violence or strong language, and main characters almost never died. The show MASH was a pioneer in changing this, notably with the surprising death of Henry Blake, played by McLean Stevenson, at the end of its third season.

The reveal deeply upset and angered viewers, and remains a memorable moment in television history. It significantly shifted the tone of MASH, moving beyond simple comedy to explore difficult moral questions and the harsh realities of war. Characters, like Loretta Swit’s Houlihan, also became more realistic and complex, moving away from being one-dimensional caricatures.

While some viewers prefer the earlier, more purely comedic seasons of MASH, the show’s shift towards blending humor with drama felt natural. The series had touched on serious topics even before its third season—one episode featured a surprise death during surgery. However, starting with the fourth season, the show balanced laughs and emotional moments more evenly.

Henry Blake’s MASH Death Is One Of TV’s Most Groundbreaking Moments

Considering it’s been 50 years, and shows like Game of Thrones now frequently kill off major characters, Blake’s death might not seem like a huge shock today. However, back then it was groundbreaking because it was one of the first times a TV show had done something like that, and the surprise wasn’t ruined by leaks or spoilers.

Though not the show’s central figure – a reason why actor McLean Stevenson departed – Blake was incredibly popular with viewers. His last episode, “Abyssinia, Henry,” led the audience to believe he was simply returning home, making the shocking news of his death – delivered by Radar in a plane crash message – a complete surprise.

The decision was hugely debated when it first happened, and it took other shows a long time to follow suit with similar plotlines. However, viewers eventually recognized it as a powerful choice. It was a sad, but appropriate, conclusion for a beloved character, and it reinforced the show’s message about the horrors of war.

It’s interesting that MASH never killed off any of its main characters – CBS was likely worried about facing another public outcry. This event remains infamous and signaled a shift for the show, transforming it from a strong comedy into a critically acclaimed dramedy. It went on to influence shows like Scrubs and even Prime Video’s Fallout.
