WBIR debuted a new logo which consists of the number 10 from the previous logo and a heart located in the middle of the number. The station also recieved a new tagline called Straight from the Heart. During this logo's run, channel 10 switched from CBS to NBC on September 10, 1988 due to WTVK (now WVLT-TV, channel 8) having a weaker signal than WBIR and NBC being succesful in the ratings. The station also debuted a new tagline to anticipate the switch called NBC and Channel 10, A New Beat of the Heart.
