Colm's RTE colleague's have led the tributes with fellow Sports department stalwart Des Cahill describing him as "a fantastic colleague with a hearty and infectious laugh with bundles of energy and the worst horse racing tips in Ireland."
RTE soccer legend, Paul McGrath simply tweeted "Colm Murray. One very special man. RIP."
Hector O'Heochagain, now of 2FM, declared "There goes a great sportsman, Irishman & a man who loved the Gi Gi's."
Enda Kenny joined the tributes, calling Colm the "voice of Irish racing for many years."
Numerous sporting organisations from Horse Racing Ireland through to the GAA and the IRFU have paid tribute to the broadcaster.
One of the country's most iconic broadcasters, with an instantly recognisable voice, Murray was the frontman of RTE's Six One sports news since 1988.
In early 2010, he was diagnosed with motor neuron disease, after which he continued to work for RTE for another year.
In early 2012, Colm's battle with motor neuron disease was the focus of a memorable and touching RTE documentary called 'MND - Inside Track.'
The airing of the documentary prompted a massive response with so many people praising Colm's "dignity, courage and humour" in the face of the disease and calling for increased funding to help those fighting the illness.
This evening at 10pm, RTE Radio One will broadcast a special one hour long interview with Colm conducted by Sean O'Rourke back in January 2012.
