Using sed with a foreach loop

So I am back again beating my head against the wall with a shell script and getting a headache! I want to change each year in a file (1980, 1981, 1982, 1983, etc.) to the same year followed by a tab.

The input is "blah blah (1980) blah blah".

I want to get "blah blah (1980 ) blah blah".

Code:
foreach year (1980 1981 1982)
sed -e 's/$year/$year     )/g' input_file > output_file

only changes the last year. Does sed need something special with foreach?

Thanks much to anyone in advance, Peggy
