It was never clear in that period whether it was the end of the previous year's season or the start of the new year's season. I'm sure that the new year was also regularly used by commentators and pundits in the first half of the 1980s. Of course, since 1986, when it was moved back to late in the year, they have been anxious to paint the YEC as always being at the end of the year.
