In the passage it suggests that goosed means that money will be invested in the magazines. The usual meaning of goose as a verb is to touch someones bottom without asking!

poke someone in the bottom

This confused me too, as I was only aware of the slightly vulgar meaning. But I've done some googling and found some other references to do with business, and also this dictionary entry: —v.t. 1. Slang.to poke (a person) between the buttocks to startle. 2. Informal. a. to prod or urge to action or an emotional reaction: The promise of time off may goose the workers and increase profits. b. to strengthen or improve (often fol. by up): Let's goose up the stew with some wine. c. to increase; raise (often fol. by up): to goose up government loans in weak industries. d. to give a spurt of fuel to (a motor) to increase speed. So the second meaning seems to make sense. It seems to mean boost/improve. You can even see a connection in some ways with meaning number 1 - a sudden shock? kick in the backside?
