Parakala resigned his RGNIYD assignment in 1994 in order to contest the Legislative Assembly elections from the constituency which was earlier represented by both his father and mother. That election saw the return of N T Ramarao to power with a landslide victory.Congress party was decimated in the state. Parakala lost the election with over 20,000 votes margin. Although unsuccessful, his imaginative campaign was admired and talked about throughout the state. Perhaps for the first time a constituency-level manifesto was released for Narasapuram. A short campaign video specially shot for the election was released and exhibited throughout the constituency by moving television sets and video cassette players manually from place to place. Audio cassettes of Parakala's public speeches were widely circulated in the constituency. Such campaign techniques were quite rare, although not completely unknown, during those days when even the television penetration was very low.
