Netflix (NASDAQ: NFLX) executives are no doubt eager to turn the calendar from August to September. The spectacle of the Olympics likely pushed subscriber growth numbers down around the world. Combined with elevated cancellations from its recent price increase, the major TV event had to have affected new member additions. Altogether, executives forecast adding just 2.3 million subscribers in the quarter that closes on Sept. 30 — down sharply from the 3.3 million it added in the prior-year period.
