Action camera maker GoPro is cutting the jobs of about 7% of its workforce (roughly 105 people) after poor sales during the fourth quarter. The company recently slashed the price of the notoriously pricey Hero4 Session. The company said it likely made $435 million in revenue during the fourth quarter, way under analyst projections of $510 million. A limited market for people who want to film their active lives and lower-priced competition is the cause.
