"television" versus "tv" keywords - How should they be merged?

I've noticed a lot of bifurcation in various keywords that include "tv" and "television." How should those keywords be merged?

My proposal would be as follows:

(1) Use "tv" in keywords that refer to the actual content that appears on television, including shows, programs, series, commercials, news, etc.

(2) Use "television" in most other keywords.

My proposal seems to be where the bifurcated keywords are already headed, in terms of the numbers of existing titles (with some exceptions).

Here is a list showing exactly which keywords I am proposing should be merged. The mergers would be in the directions of the arrows:

1. Keywords to Merge in Favor of "tv"

television-ad (5 titles) --> tv-ad (174 titles) --> tv-advert (190 titles) --> tv-advertisement (6 titles)
