Why are the letters "er" highlighted in Bell's new marketing Campaign?

Question

I'm pretty sure this ad campaign is only in Canada, though i may be wrong

Answer 1

This is just a part  of their advertising campaign. They were just "trying" to be clever.

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.

hope i helped. :)
