What does the bolded "er" in the Bell ads signify?

Answer 1

I'm not sure it really means anything, but i did find thid paragraph that might  help. :)

To tie the advertising even more closely to the concept of "better" and underline the range of product and benefits Bell offers, the English campaign also makes liberal use of words ending in "er" — faster, easier, music lover, gamer, worker, talker, texter, multitasker — which was also the basis of the company's recent advertising teaser campaign.
