Tradition or laziness?

Ever notice how advertisers get a little lax around the holidays and rerun the same ads year after year?  I can think of three commercials off the top of my head that have been repeated for maybe five to ten years.  Penny pinching?  Do they think if they play them enough it's tradition?  Are these really classics and I'm just a Scrooge?  You decide.

Exhibit A, the fainting M&M:

Winter-Time

Late lies the wintry sun a-bed,
A frosty, fiery sleepy-head;
Blinks but an hour or two; and then,
A blood-red orange, sets again.

Before the stars have left the skies,
At morning in the dark I rise;
And shivering in my nakedness,
By the cold candle, bathe and dress.

Close by the jolly fire I sit
To warm my frozen bones a bit;
Or with a reindeer-sled, explore
The colder countries round the door.

When to go out, my nurse doth wrap
Me in my comforter and cap;
The cold wind burns my face, and blows
Its frosty pepper up my nose.

Black are my steps on silver sod;
Thick blows my frosty breath abroad;
And tree and house, and hill and lake,
Are frosted like a wedding-cake.

- Robert Louis Stevenson
