[6][7] He became the editor of the Barbados Daily News in 1961, where he worked with retired cricketer Everton Weekes,[8][9] and covered the West Indies tour to England in 1963.

[4][6] He was a member of the BBC's Test Match Special commentary team from 1966,[5][10] and also commentated on television for Channel Nine in Australia[11] and Sky Sports.

"[14] Cozier was known for his knowledge of statistics; during a Marylebone Cricket Club tour in 1967, Brian Johnston played a practical joke on him by pretending that they were on air and asking him to recite the exact bowling figures and birthdays of the entire West Indies team, which he was naturally unable to do.

[14][16][17] In 1994, Cozier wrote of Brian Lara's record-breaking innings that "there was no real surprise among his countrymen, simply the feeling that his inevitable date with destiny had arrived rather more suddenly than expected.

[16] In 2007, Cozier used a lunch break in a Test match at the Riverside Ground to read a spoof email asking about cricket in Mexico; fellow commentator Jonathan Agnew had to explain the joke to him.

"[19] The parties that he hosted for his media colleagues, held at his small wooden holiday home on the east coast of the island whenever there was a Test match in Barbados, were described by Vic Marks as "legendary".

[6][2][14] Cozier wrote the definitive The West Indies: 50 Years of Test Cricket, with a foreword by Garfield Sobers (1978).
