Fulfilling its months-long destiny, one anointed by the Super Bowl, NBC closes out the 2014-15 television season as the No. 1 network — despite a last-minute narrowing of the race by CBS and a resurgent ABC. The victory lap, which the network did not temper during its May 11 upfront presentation, is bittersweet. Its average 2.4 rating among adults 18-49 in primetime was achieved largely on the merits of the NFL and The Voice. The highest-rated network on the dial was also the only broadcaster to fail to launch a single new hit this past season (as evidenced by its modest renewals).
