I just wanted to point out that the plural form of a noun does not use an apostrophe. Possessive nouns, and contractions, use an apostrophe--as follows: It's (contraction of "it is" or, in this case, "it has") been standard in the program descriptions lately. If that plural word, "descriptions," was in the program guide, it would have been spelled "description's." You could use the possessive case and say, that program description's punctuation is incorrect!
Using correct spelling and punctuation indicates a degree of competence and knowledge that incorrect usage of English does not. For this reason, I feel compelled to bring this to your attention.
Thank you.
